How to Use Infrared Thermometer Gun

Have you ever heard about an Infrared thermometer?

If yes, then you probably know it’s a device used to get temperature readout. One needs it for scanning particular segments of any area or object. There’s a built-in laser to complete this process.

It is mainly essential for usages that need to figure out the various surface readings. For example, food items, automobiles, ventilation or the wall’s surface.

Today we will talk about how to use infrared thermometer for such various needs.

How to Use Infrared Thermometer Gun Properly

Step by Step Usage Guide, FAQs

Below we would discuss using this tool and some facts about its accuracy. Also, I will be answering your most asked questions in a section. Keep on Reading!

Start by Turning on The Device.

Depending on different models of an IR thermometer, the turning on step may vary. So, you need to refer to your particular model’s switching-on system. There should be information regarding this in the included user manual. So, check there.

  1. If you own Model IKR-2, start this device by pressing the button called C/F while triggering at the same time.
  2. In the case of using Model IR-GUN-S, you should hold Measure labeled button and also press C/F button at the same time.
  3. Finally, for Model IR-IND you need to hold Measure button to press down labeled button to make it start.

Let the Laser Point Toward the Target

After turning the device on, there should be a circular laser light beaming. Now at the targeted object that needs a reading, point this laser light carefully. Of course, you can do this by maintaining a distance. However, there’s a limit to this distance. It can’t be infinity you know. Depending on what particular model you are using, this distance should be specific. It should be mentioned in the user manual again.

However, in most cases, it’s good to stand closer to the target object as much as possible. The maximum distance that is okay to keep for measurement is known as Spot Ratio. Sometimes, it’s also called Distance to Spot Ratio.

Once You Are Done with The Task

Until you complete the temperature reading, keep on pressing trigger on an object. If you release this trigger, the device won’t work anymore since laser light will stop emitting. Once the readings are complete, turn device off by gradually releasing this trigger.

Keep in Mind:

  • The laser has a negative impact on eye chancing permanent damages. So never look at the beam directly.
  • In case you are measuring liquid or soft foods, make sure to stir it well.
  • Unexpected ambient temperature changes are the main reason for inaccurate readings. So, in case of a walk-in-cooler, place the thermometer inside 20 minutes earlier. This way the final result is more accurate.
  • The thermometer and product should have no barrier in between. So, don’t forget to take the covers off.
  • For accurate readings, it’s important to clean the thermometer regularly.
  • Let griddle or pan have oil in its surface before checking the temperature. This will give better reading results.

Infrared Thermometer Accuracy

Infrared Thermometer Accuracy

The main factor that connects with an infrared thermometer’s accuracy is emissivity. This term usually means the rate of infrared energy emitted from a substance. And this is usually calculated with a 0 to 1 scale.

With a 1 scaled object, the surroundings infrared energy gets completely absorbed. It chooses own infrared energy emission only. This emissivity factor can make an impact on the thermometer’s temperature readings.

Objects that have low emissivity tend to give inaccurate results. For example, stainless steel and aluminum show pretty inaccurate results. Applying a thin grease layer over these surfaces is a good solution. And this will help in increasing radiation dramatically.

Some thermometers come with emissivity settings for this problem. It can be fixed or adjustable type depending on what model you are buying. For simplified operation, a fixed setting will help you better. These are great for almost every object including food items.

However, you don’t want to compromise accuracy of low emissivity materials. In that case, the adjustable settings are best suited.

 Frequently Asked Questions

Can you use infrared thermometer on humans?

It depends. Usually, the thermometers for body temperature readings use a bolometer. This is a great component for getting a good result on 35 to 45-degree Celsius. And this is supposed to be pretty accurate when calibrated with black body radiator to within 0.05 degree Celsius. Usually, best approximations here are the human ear and mouth area.

How to check accuracy of infrared thermometer?

It’s simple but only when you have a surface that has a temperature you already know. This stable surface will help in verifying the accuracy of an infrared thermometer. You need to compare the readings using an immersion type thermometer here. This type usually stays below the surface of a semi-solid or liquid. The experiment is however not controlled.

Are infrared thermometers accurate for cooking?

Using an infrared thermometer for cooking purposes is pretty uncommon. However, it can very well give you a spot-checking opportunity for meals. And that way, you have a good check on whether food is hot throughout the day. At a local restaurant. These are pretty good to use for the buffet. It helps to keep several courses at the right temperature. It also lets you know whether the meal needs your touch for reheating.

Looks like we have reached the end for today! Hopefully, you have a better idea of how to use infrared thermometer now. No matter what object you need the infrared thermometer for, choosing a good and functional model is the key here.

So, make a wise choice when buying one. Also, do follow the right instructions given on included user manual. Usually, people don’t go through that manual when it already comes with most of the usage details clearly.

Good Luck on an Accurate Temperature Reading Using That Infrared Thermometer of Yours!
