Etekcity Lasergrip 630

High Range Thermometer

Although infrared thermometers give us some advantages in regard to measuring temperatures of objects that would be otherwise nearly impossible to measure, there still tend to be a lot of limitations with these devices. For one, many of them tend to have a limited temperature range, but more importantly, many also have a very limited distance range. This can make getting the temperature of certain objects quite difficult even with some of the higher-end infrared thermometers. In these instances, the benefits of an infrared thermometer seem to be negated by the challenges they face.

The Etekcity Lasergrip 630 Dual Laser Digital Infrared Thermometer is one model that is made to work well in situations where most other infrared thermometers fail. The ratio of the distance to the object to the measurement spot is 16: 1, which allows you to measure the temperature of objects that are far enough from the instrument, for example, the air temperature created by a wall-mounted air conditioner. This is well beyond what most other models offer in regard to the distance range. Even the temperature range of -58 °F to 1076 °F is higher than any other model that we review here, making this model the best choice where others will have difficulty with measuring.

Etekcity Lasergrip 1080

Device for Appealing Price

The Etekcity 1080 non-contact infrared thermometer is an excellent choice for people who need to use a reliable device for a reasonable price. Though having just a few additional functions, this laser thermometer is suitable for a variety of household tasks, such as repair works, cooking, or checking the temperature of the water for a baby bath. Despite being fairly affordable, this non-contact laser thermometer works really well. This device has a built-in laser to help you direct heat sensor right at the spot you need. Unlike its wallet-friendly counterparts, this temperature gun has quite a high distance-to-spot ratio, 12:1. Therefore, the distance to the object can be quite long.

Among the usability features of the Etekcity 1080, we'd like to note its wide temperature range that varies within -58°F to 1022°F, an impressive result which is more typical of pricier models. The other features include a data hold function that allows fixating readings for their further comparison and analysis, and auto shut-off that switches the device off after it's been idle for a certain length of time. Like on most infrared thermometers here you will find a backlighting that can be enabled and disabled manually, depending on the surrounding lighting conditions.

Nubee NUB8500H

Fit for Any Job

The Nubee NUB8500H is one of the best devices in terms of measurement accuracy. Unlike lots of other non-contact thermometers, this one has a unique EMS adjustment function. That might sound overly scientific, but here's a brief explanation: each material has its emissivity, and if a laser thermometer is fitted with the emissivity adjustment, all measurements will be more accurate. You just need to check a special table with the emissivity of various articles, then adjust the settings on the Nubee laser thermometer so that the readings will be as accurate as possible! Needless to mention, this infrared thermometer remembers the maximum temperature reading; professional mechanics know how useful this function is, particularly for repairs of industrial equipment and in construction works. If the battery is running low, you will notice an indication icon on the display.

There are more functions we would like to mention. Thanks to the Data Hold function, the Nubee NUB8500H can store several temperature readings for you to be able to compare them later on. The metrics supported include Fahrenheit to Celsius temperature scales. You can choose the one that you're more accustomed to. If it wasn't for a full-plastic casing being prone to scratches and damage we could give the Nubee NUB8500H one of the highest scores. For now, we will only say that this thermometer is very precise and accurate and can last in a while under careful treatment.

Comparison of Non-contact Laser Infrared Thermometers

What is an Infrared Thermometer

There are many situations, where a regular thermometer can't be used, such as when you need to measure the temperature of moving objects, electrical circuits, mechanical equipment, and other things that cannot be touched by hand. While you could definitely resort to using some other methods of measuring the temperature of these surfaces, a more convenient and - more importantly - more accurate way would be to use an infrared (or laser) thermometer.

IR thermometers will come in handy not only when you work on mechanical equipment or vehicles but also anywhere else in your home for measuring temperature from a distance.

Using an infrared thermometer is as easy as anything. All you need to do is direct it at an object you're working on and the tool will do the trick. And if it has an auto shut-off feature as well, you will be able to use it with little to none supervision at all.

If you want to get yourself only the best infrared thermometer rather than waste money on cheap knock-offs, this review is tailored specially for you. We offer you the selection of the best-selling IR thermometers along with the key specs to consider before making a choice. We hope our guide will help point you in the right direction.

Another device that will come in handy in different industries and work environments is a moisture meter. If you don't have one yet, make sure to check out this review too.

Best Infrared Thermometers

What Features to Compare

Temperature Range

There are several important features to consider when choosing a decent infrared thermometer. And the temperature range is among the most important ones since it determines the scope of application of the thermometer. The IR thermometers with a relatively narrow range are suitable for household use; you can use them to detect a draft or check how well the doors and windows are insulated. These temperature guns are also widely used in cooking. The laser thermometers with a wide temperature range are suitable for use by professionals; they are common at construction and industrial sites.

Distance-to-spot Ratio & Accuracy

The next important tech spec to consider is a distance-to-spot ratio. This ratio means the size of the spot on the object compared to the distance to it. If you mostly measure the temperature from small distances, you can opt for a device with a small ratio. And vice versa, the farther the object is, the higher the ratio a gun should have. As far as accuracy is concerned, if you need an infrared thermometer to use at worksites, opt for accurate non-contact thermometers.

Conveniences

Finally, consider whether the chosen thermometer is convenient to use. Some of the features just cannot go underestimated. Most IR thermometers, for example, can retain the maximum reading taken during measurements, so you can compare several readings further in use, knowing the highest temperature detected. Other thermometers feature a memory option, allowing you to check several readings taken during a different period of time. Also, we'd recommend you to consider what type of material the case of the gun is made of. This can be really important, especially if you work in quite dusty and humid environments. Opt for a dust-proof and water-resistant infrared thermometer with a rubberized grip.

FAQ:

Q: How does an infrared thermometer work?

A: Each infrared thermometer has a special sensor called a thermopile. This sensor detects infrared radiation reflected from an object, turns it into the heat which then transforms into electricity. The more electricity, the higher the temperature of the object is.

Q: What does ‘infrared’ mean?

A: Infrared radiation is a part of electromagnetic spectrum. This kind of radiation is, actually, the heat that our skin feels. Though infrared radiation is generally invisible, it might emit light at really high temperatures.

Q: What are infrared thermometers used for?

A: IR thermometers allow measuring a temperature of distant objects with the help of a special heat sensor. It means there is no need to contact the object; instead, just direct the laser beam onto it, and the device will show you the temperature. For example, laser thermometers are used to measure the temperature of air vent ducts, engines, machinery parts, and even kitchenware.

Q: The manual has a confusing spec called ‘distance-to-spot’ ratio. What does it mean?

A: In a nutshell, it means the size of the spot on the object being measured from a certain distance. For example, if a non-contact thermometer has a distance-to-spot ratio of 12:1, it means you will get a 1’’ wide spot at the distance of 12’’.

Q: What is the temperature range most IR thermometers support

A: Laser thermometers are used for a large scope of industrial and construction jobs, so most of them offer quite a wide range. The minimum temperature is usually around -60 degrees F, whereas the maximum amounts to around 1,600 degrees F.

Q: What does ‘emissivity’ mean?

A: Without going deep into technical details, emissivity is the ability of a certain material to emit infrared radiation. It’s measured from 0.00 to 1.00. The higher the emissivity of the material is, the more accurate the readings of the laser temperature gun will be. Most devices come with a useful table with the emissivity of different materials; you should use it to get accurate readings for low-emissivity materials (such as aluminum, for example).

Q: Can I use a laser thermometer to check the doneness of food?

A: No. IR thermometers can measure the surface temperature only. If you need to know the internal temperature of solid foods, a probe thermometer must be used.

Q: Is it necessary to calibrate non-contact thermometers?

A: Yes. The frequency of calibration is usually specified in manuals. As usual, laser temperature guns are sent back to manufacturer and put into calibration in appropriate conditions.

Q: How do I know when it’s time to calibrate an IR thermometer?

A: Most non-contact temperature guns perform a check-up of all functions when they are switched on. If calibration is required, an error message is displayed to a user.

Q: Can I use an IR thermometer to measure the temperature of baby formula?

A: Yes. However, you should stir it well before taking the measurement so that the formula has the same temperature as a bottle or a bowl. The same approach is applied to measuring water temperature in a baby bath.
