An infrared thermometer is also known as a laser thermometer. Infrared thermometers measure the heat emitted as infrared light, which is invisible to the open eye. Basically, an infrared thermometer is widely used to measure fast surface temperature in the science and the food industry. However, can infrared thermometer measure water temperature?

It will depend on your infrared thermometers and their workable measurement range. The infrared thermometer is gaining popularity due to the non-touch temperature detection method from a distance. It’s ease of use makes an infrared thermometer the most reliable and effective surface temperature measuring method. Read this instructional article to know the proper uses of infrared.

Can Infrared Thermometer Measure Water Temperature?

Therefore, can infrared thermometer measure water temperature? As I mentioned above, an infrared thermometer can measure surface temperature. The infrared thermometer acts with its sequences of object glass and mirrors to detect the infrared energy that emits from the objects. Due to their lightweight and portable construction, anyone can use it anywhere.

Can Infrared Thermometer Measure Water Temperature?

In fact, it comes in handy to determine the actual temperature of hazardous materials, frozen foods, and any type of liquids. Additionally, the infrared forehead thermometer temperature measuring process prevents cross-contamination and doesn’t need to clean after use.

Limitations of Infrared Thermometers

There is no doubt that an infrared thermometer is handy, thus allows determining different surface temperatures with ease. However, before developing too much confidence in infrared thermometers, you should understand their limitations.

Limitations of Infrared Thermometers

  • An infrared thermometer only measures surface temperature and doesn’t measure the internal temperature of any materials. Therefore, an infrared thermometer is not a substitute for determining interior temperatures in foods or other elements.
  • It necessitates proper adjustments depending on the ground or materials being measured.
  • Temperature measurement could be affected by moisture, dust, frost, smoke, fog, or other airborne particles.
  • IR thermometers don’t work through other materials, for example, liquids, glass, or other clear surfaces. Even if any visible light can pass through them. In other words, if you point an infrared thermometer at a window, it will measure the windowpane temperature, not the outside temperature.
  • It could be temporarily influenced by proximity or a radio frequency with an electromagnetic field force of 3 volts per meter or higher.

How Do You Measure the Temperature of Water?

Though measuring water temperature isn’t tricky, you should follow a few steps to get an accurate result. Here are some measures you have to maintain to measure the water or any liquids surface temperature with an infrared thermometer.

How Do You Measure the Temperature of Water?

Step 1:

Read the Manual: The infrared thermometer has various types and diverse calibration systems to determine any object’s temperature. You should read the user manual and learn the calibration setting for your infrared thermometer. It will help you to measure water temperature quicker and accurate.

Step 2:

Prepare the Vessel: The vessel is an aluminum beverage can, and it should be stripped using electrical tape on its around. The electrical tape will prevent infrared energy reflected from the can transverse your reading.

Step 3:

Pour the Water: Now, pour the water that you want to determine the temperature. You can use a funnel to pour water from any large pot. Besides, you have to be careful if measuring hot water.

Step 4:

Point the Infrared Thermometer: Get your infrared thermometer and point to the thermometer’s laser end toward the vessel. You should maintain the proper distance between your thermometer and the vessel. Distance will be mentioned in the user manual, so read the manual carefully.

Step 5:

Wait for the Results: Your result won’t take much time. After a few seconds, the thermometer will display results on its digital display. To get a faultless result, take the result twice. You should keep in mind that your temperature could be different if you take measurements at two different times.

Advantages Of Using Infrared Thermometer

An infrared thermometer has lots of advantages over any regular thermometer. First of all, it is effortless to operate, and anyone can understand the reading. Here are several benefits of using an infrared thermometer for temperature measurement.

Advantages Of Using Infrared Thermometer

Accurate temperature reading:

An infrared thermometer can give instantaneous temperature measurement and precise reading. Infrared thermometers design and its measurement method allow users to get reliable and accurate temperatures in no time.

Easy to Read:

The most infrared thermometer comes with a digital display, which shows temperature as a large number. Besides, the IR thermometer has a backlit so that users can see the temperature reading in the dark.


While a regular thermometer needs contact with skin materials to determine temperature, the IR thermometer doesn’t come into contact. This feature minimizes risks of cross-contamination by keeping the distance between sick persons and the thermometer. Therefore, every family member can use one thermometer without transmitting an infection.

Multiple Uses:

IR thermometer not only measures body temperature but also measures food, liquid, and any other surface temperature. Some infrared thermometers have a smart memory function to save previous reading data and fever alarms. If the thermometer detects very high body temperature, it can let the user know by beeping.

Compact Construction:

The infrared thermometer comes with lightweight and safe construction. Besides, an infrared thermometer is completely free from mercury, which could harm the human body. Lastly, an infrared thermometer runs using a removable battery so the user can change or replace it when required.

Final Thoughts

In conclusion, Our main focus was to let you know can infrared thermometer measure water temperature? I think you got a clearer view of this topic.  An IR thermometer is a useful equipment that can measure the temperature of almost any material. Besides, it doesn’t need direct contact to measure the temperature of any liquid or human body. That’s why people can use it for measuring hot to cold at any type of material temperature.
