If you're like most people, you probably don't know too much about infrared thermometers. You may have seen them used on TV shows or in movies, but you might not know what they are or how they work. In this blog post, we'll give you a crash course in infrared thermometers. We'll explain what they are, how they work, and why you might want to consider buying one for your home or business.

What is a Non Contact Thermometer?

What is a Non-Contact Thermometer?

A non-contact thermometer is a temperature measurement device that uses infrared technology to measure an object's surface temperature without making physical contact with it. Non-contact thermometers are often used in situations where maintaining physical contact would be impractical or dangerous, such as in the monitoring of industrial furnaces or electrical equipment.

Additionally, they can be used to measure the temperature of moving objects or those at a distance, making them ideal for food service or medical applications. Most non-contact thermometers use infrared technology, but there are also devices that use lasers or ultrasound. When selecting a non-contact thermometer, it is important to consider the accuracy required for the application, as well as the distance at which the measurement will be taken.

How Do Non-Contact Thermometers Work?

How Do Non Contact Thermometers Work?

Non-contact thermometers are devices that measure the temperature of an object without coming into physical contact with it. They work by using a technology called infrared thermography, which is based on the principle that all objects emit infrared radiation. This type of radiation is invisible to the human eye, but can be detected by special sensors. 

When the sensor comes into contact with the infrared radiation, it produces an electrical signal that can be used to calculate the object's temperature. Non-contact thermometers are often used in situations where it is not possible or practical to physically touch the object, such as when inspecting objects from a distance or in a hazardous environment.

What to Look for When Purchasing an Infrared Non-contact thermometer

If you're in the market for a non-contact thermometer, there are a few things you'll want to keep in mind.

  • The accuracy of the thermometer. It's important to find a thermometer that can provide accurate readings.
  • The range of the thermometer. Some thermometers only work for certain temperature ranges, so you'll want to make sure the one you choose can measure the temperatures you need.
  • Size and weight of the thermometer. A heavier thermometer may be more difficult to use, and a smaller thermometer may be more difficult to read.
  • Make sure the thermometer can take readings in both Celsius and Fahrenheit.
  • Check to see if the thermometer has a backlit display, which will make it easier to take readings in low-light conditions.
  • Consider whether you want a battery-operated or USB-powered model.

Cautions When Using a Non-Contact Thermometer

First, make sure the batteries are fresh and the device is properly calibrated. Second, always point the infrared sensor towards the area you want to measure. Third, be aware that some objects can reflect heat, so if you're not getting an accurate reading, try moving the sensor around until you find the sweet spot. Finally, remember that non-contact thermometers aren't suitable for every situation. If you're dealing with a very small object or area, it's best to use a traditional contact thermometer.

General Tools Non-Contact Thermometers: 4 Effective Options

Choosing the best infrared thermometer starts with establishing the primary purpose for using it. Will you use it to read body temperatures, for cooking, or for more industrial readings? Infrared thermometers have different sensitivities and effective ranges, so you must be specific when making your choice. 

Here are four options from General Tools:

1. Non-Contact Infrared Thermometer, 10:1 Distance to Spot Ratio

Non Contact Infrared Thermometer, 10:1 Distance to Spot Ratio

The IRT217 Infrared Thermometer is a gun-style meter that offers an easy and safe way to measure surface temperatures. It can be used around the house for tasks such as identifying hot or cold spots, cooking, automotive work, electrical projects, HVAC maintenance, and more.

The IRT217 features a white on black screen for clearer, easy-to-read measurements. The unique targeting ring makes measuring more accurate, since it shows the full area that is being measured rather than just a laser like many other models.

3. 8:1 Non-Contact Infrared Thermometer

The IRT207 Laser Thermometer is powerful and accurate, making it perfect for various applications including HVAC/R, plumbing and heating, electrical work, automotive repairs, and general industrial use. With a wide temperature range of - 4 to 608 degrees F ( -20 to 320 degrees C), a backlit screen, and a laser pointer to see where you’re measuring, the IRT207 is a fantastic choice.

2. 6:1 Pocket Infrared Thermometer

6:1 Pocket Infrared Thermometer

The IRT102 Laser Thermometer is perfect for quickly and easily checking the temperature of surfaces and objects from a distance. Its features make it ideal for electrical troubleshooting and HVAC equipment maintenance.The IRT102 is compact and great for portability, coming with a handy lanyard.

4. Hawkeye Hand-Held Infrared Thermometer | Non-Contact Human Body Temperature Readings

Hawkeye Hand-Held Infrared Thermometer | Non-Contact Human Body Temperature Readings

The Hawkeye™ NCIT100 is a special infrared thermometer that gives readings of human body temperature with an accuracy of ±0.4°F (±0.2°C) and a response time of less than two seconds, allowing mass temperature screening in workplaces, public events or social gatherings. You can also switch the reading to show output in Fahrenheit or Celsius. It is recommended to only use this thermometer for measuring human body temperature.
