Best Infrared Thermometers

If you need to measure the temperature of an object at a distance, then you need to use a best infrared thermometer for this.

Thermometer used for several purposes:

1. Baking bread. I usually let the dough rise inside the oven which I preheat to a temperature of 100 to 110 F. With this thermometer I can measure the thermometer within one second after opening the oven door slightly. Works very well. Out of curiosity I checked the oven temperature after it started baking. Immediately after the oven signals that it has reached 350 F. I checked the temperature which is the 370 F. Within a minute it indicates a temperature close to 350 and then keeps fluctuating slightly around that temperature.

2. I defrosted my refrigerator and freezer. The refrigerator has white panels and after it was defrosted the temperature measured was within 1 degree of room temperature. Once it was cooling down I could easily measure the steadily lowering temperature and after 24 hours it had reached thee final temperature. The freezer compartment was temporarily below 0 F and then “stabilized” at the (adjustable set point. The temperature in a refrigerator is never constant.

3. I measured the temperature in my house by pointing the thermometer at the inner wall and the furniture. It was always within 1 degree of the thermostat set point.

Such an instrument will help you measure the temperature any object without having physical contact with it.

I have a cheap IR thermometer and find it useful in many applications, but I now need a unit with greater accuracy, temperature range, adjustable emissivity, and dual lasers to mark the size of the measurement area. I have other Fluke equipment which has proved rugged and reliable and the 62 MAX Plus has the temperature range I wanted. I won’t go through all the features as those are well covered by other reviews, but I feel more information on emissivity and the rotating lasers is needed.

Emissivity: All IR thermometers depend on the emissivity of the surface they are measuring. The 62 MAX Plus comes set to 0.95, but has a selectable range of from 0.1 to 1. An EMS setting of 0.95 is a good value for brick, chipboard, fired clay, concrete, formica, glass, PVC, most paints, tar, rubber, sand, soil, masking tape, floor tile, and water in all forms except snow. Snow and most types of bare wood have an EMS closer to 0.85. A surprise is gravel with an EMS of only 0.28. What that means is that unless you select an EMS of about 0.28 the 62 MAX Plus will give you an incorrect temperature reading of a gravel surface. You can find tables of emissivity for common materials by doing an internet search for “emissivity table”. A lot of times you don’t care about the actual temperature so much as how it has changed over time or relative to other spot.

Dual lasers rotate to pinpoint the edges of the measurement area: The laser beams spread out in the same 12 to 1 ratio as the optical resolution of the IR sensor, which makes it easy to see the size of the spot you are measuring. The “rotate” part refers to the two laser spots changing their position relative to the 62 MAX Plus unit depending on the distance to the surface being measured. Holding the 62 MAX Plus with the readout horizontal, the two laser spots describe a vertical line (if you connected them) at the unit out to about 2 inches. As you move further away the spots appear to rotate counter-clockwise to describe a horizontal line at about 24 inches. Moving further away the spots continue to rotate until they describe a line from 2 to 8 o’clock at 10 feet and beyond. In practice I’m not sure what value the rotate feature has other than perhaps as a marketing point.

The eT650D from ennoLogic is a noncontact precision infrared thermometer that allows you to measure the temperature of an object from a distance by sensing its radiated infrared energy. It is a feature-packed instrument with countless home and industrial uses that include cooking (pizza, grilling, candy and chocolate making, tea, beer and wine home brewing), food safety, refrigeration, forging and metalworking, soap making, automotive, A/C, HVAC, pool, and even animals (reptiles, chickens).

Dr. Madre Digital Infrared Forehead Thermometer 

After spending WAY too much time searching through thermometer reviews, deciding to try this one since it was the only one a number of reviewers seemed to think showed a consistent and accurate temperature. I couldn’t be happier! I don’t know what is different about this than all of the other ear or forehead thermometers that get good reviews until you see how many people say they’re totally inconsistent, but this one seems to really work. Tried it on 5 different people as soon as I got it. Got different results for each person, and went back 10 minutes later to retest two of us, with totally consistent re-readings to the decimal, including picking up on a near-fever that one of us had that I hadn’t even noticed until using this.We love our new thermometer! It is a lifesaver for late night fevers and tired parents with sick kids.

We can check their temperature while they sleep without them even knowing. No more waking them unnecessarily when they need their rest. No more guessing what the screen says either! The screen lights up nicely and it will even tell you their temperature if you want it to. This works great on adults too! It is accurate, easy to use, a great size, and worthy of the five stars!!This thermometer comes with really good documentation and a nice case. The thermometer did not power up at first, but worked when I removed and reinserted the batteries.

Overall this is an excellent product. The grip is nice, the display screen has a backlight and you can’t beat the price.

A simple way to test the accuracy of this thermometer is to measure the temperature of a pot of boiling water. This will roughly give you a temperature of 212 F. Boiling water, in equilibrium (or the entire fluid being the same temperature) will maintain 212F no matter how quickly the water is evaporating. The reason this is a rough estimate is that the boiling temperature of water changes with salinity and altitude.

The thermometer I received was reading around 208-212 F. So how does this compare to the top end model? I am an engineer who provides safety related components to nuclear power plants. We use the $200+ model which is calibrated by a separate vendor. Our calibration standard is 1.5C which is 209.3F as our lower end tolerance. So this thermometer would NOT be suitable for qualifying safety related components for nuclear plants. Except you aren’t trying to qualify safety related components.

Works as expected.
It’s original purpose is to measure temperature on computers and air conditioner appliances, and food, why not?

Incredibly it’s first debut was on a kid with fever. Here is the funny story!
On a family meeting we found that a nephew wasn’t playing with the other kids, so my wife sensed she was warm and she attempted to find the oral thermometer to no avail.Here is where my gadgets come to play it’s part, funny to say but: I turned off the laser pointer, asked her to look away then pointed in the forehead, about 7 to 10 inches away.

1st reading was 35.7 C and raising,
after 1 minute made a 2nd reading of 36.5 C,
a 3rd reading was 37.2 C, while I was shouting my wife, “bring the medicine and some ice in a towel, quick!”

– senses immediately
– able turn off blue backlight
– able turn off laser pointer
– auto off

In practice, these are used for taking a quick, general measurement of fluid temperature or identifying heat losses. I have used this at my home to identify what rooms are cooler then others, draughts around doors or windows and leaks in the HVAC system.I would greatly recommend purchasing this over the higher end thermometers. Very solid product and definitely accurate.

Etekcity Lasergrip 774  Digital Laser Infrared Thermometer 

This device is probably the best single purchase that I have made on Amazon in my three-plus years of Prime membership. It functions wonderfully as a distance thermometer, shining a tiny red dot on what I’m measuring and, based on comparison with a thermoscan camera at work, is pretty accurate across a range of temperatures from 0°F up to about 400°F.

The button that turns on the device has a very soft click, barely perceptible, so it won’t distract your faithful (or in the case of cats) persistent companions. The dot is bright and consistent, unlike other laser pointers on the market, and, (safety first) can be turned off so that fluffy doesn’t get to curious about the dot suddenly appearing on the side of a pot of boiling water on the stove.
It’s powered by a 9V battery, and the manufacturer was kind enough to include one, but buy a pack, because you’ll be using this thing on EVERYTHING!

This thermometer really works, and the dual laser is worth the few extra dollars you’ll spend for it. By using two lasers, you can not only aim the thermometer but also gauge the distance/spot size so you know exactly how much area you’re averaging. I tested against other thermometers and found this one to be very accurate. For less than $20 it feels like a much more expensive instrument because the details are “just right”.

The display shows the current spot temperature plus the maximum so far for that session. Buttons are in a good place; you can turn off the lasers or screen backlight if you don’t need them (and those settings are remembered!), and the display holds for just the right amount of time after you release the trigger.It’s educational to just walk around your house and measure the temperature of ordinary things: a human’s skin temperature runs around 87-90F, coffee from a single-pot brewer just over 140F. It’s great that it’s instantaneous and there’s nothing to clean after each measurement. Once you know these temperatures you’d be able to spot issues (air conditioning not cold enough? Refrigerator at the right temperature? What temperature is “6” on the stove?.
Is the chicken done? Laser thermometer. How cool is the A/C running? Laser thermometer. Is your house’s brick construction holding in a lot of heat in the evening? Laser thermometer. Engine block not getting coolant flow? Laser thermometer. Wildfire approaching? Run like hell.

AstroAI Digital Laser Infrared Thermometer

Great tool to find thermal leaks! Bought this to be able to find hot/cold spots around the house. Primary motive was for winter usage to find where the cold drafts are coming from but since it is spring/summer now, tested it to find the reverse. Went around the house and found quite a few door and window edges which could use some insulation to keep the air-conditioning inside.

The water cooler, freezer, fridge, gas stove, angry-wife.. all measured out as expected. Having the laser spot is more useful than I thought (did not use it around the angry-wife though).. takes guesswork out of the spot that is being measured. It came configured to measure Celsius.. which was an insult to the American in me.. but this product provides a button clearly marked “C/F”.. and one press makes it “F”! No manual needed to discover the magic combination of button presses to get to “F”. Display is backlit.. excellent for taking readings in dark. Laser can be easily switched on/off (helpful around angry wives).Other useful features: Auto shut-off.. and continuous reading when trigger is kept pressed.. helps easily find hot/old spots by scanning with the trigger pressed, 9V battery is included!

Few tips:
Manual doesn’t show how to open the battery compartment.. yes, it is the obvious handle notches you will notice on the black cover around the trigger.. takes a bit of force to open it.I don’t know how they compensate for the different surfaces but this thermometer works extremely well for my purposes.
