Handheld infrared (IR) thermometers are used in many industries and work environments to measure surface temperatures rapidly and at a safe distance. Elevated temperature can be the first sign of trouble for mechanical equipment, electrical circuits and building systems.

Are infrared thermometers effective?
Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. But with many establishments now requiring temperature checks, these hand-held thermometers are proving to be safe, quick and accurate while helping to reduce the spread of coronavirus.
Is infrared thermometer good for body temperature?
Yes. Infrared thermometers are capable of detecting the temperature of the human body. However, the device measures the surface temperature of the body. Also, infrared thermometers are useful for screening purposes, many customers find this solution to be faster with less manual setup.
What is a infrared thermometer and how does it work?
Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile. The thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat.
What is one disadvantage of using an infrared thermometer?
Only measure surface temperatures and NOT the internal temperature of food or other materials. Require adjustments depending on the surface being measured (See Adjust for Emissivity) Are not thought to be as highly accurate as surface probes measurements of the same *surface.
What is a normal forehead temperature?
The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more.
What is a normal forehead temperature with an infrared thermometer?
It would be normal to read an actual forehead skin surface temperature between 91F and 94F if using a general-purpose infrared thermometer. Some infrared thermometers have an “adjustable emissivity feature”. Some are factory set for emissivity of 0.95, or in the case of our IRFS, 0.97.
How do I check my temperature with an infrared thermometer?
Point the thermometer at the end of the person’s right eyebrow. 7. Hold the thermometer at a length of 3 fingers put together from the person’s temple (3-5 cm). The thermometer should not touch the skin.
Is wrist temperature the same as forehead?
The wrist temperature had a narrower 95% limits of agreement than the forehead temperature. The wrist measurements had a higher percentage of differences that were within ±0.5 °C than did the forehead measurements in these four groups.
How do I use an infrared thermometer on my forehead?
Aim the probe of the thermometer at the center of the forehead and maintain a distance of less than 1.18in(3cm) away (the ideal distance will be the width of an adult finger). Do not touch the forehead directly. Gently press the measurement button [ ] to start measuring.
Is infrared light safe?
Infrared light is delivered to the site of injury or inflammation at certain wavelengths, promoting cell repair. The key characteristic of infrared light is its ability to penetrate even the deep layers of the skin, providing better pain relief. Also, infrared light is safe, natural, non-invasive, and painless.
How do I know if my infrared thermometer is accurate?
To test the accuracy of an infrared thermometer requires access to a stable surface of a known temperature. You cannot verify the accuracy of an IR thermometer by comparing it to an immersion type thermometer that is beneath the surface of a liquid or semi-solid in a non-controlled experiment.
How do you use a touchless thermometer?
Using the NCIT:
- Hold the NCIT sensing area perpendicular to the forehead and instruct the person to remain stationary during measurement(s). ( See Figure 1)
- The distance between the NCIT and forehead is specific to each NCIT.
- Do not touch the sensing area of the NCIT and keep the sensor clean and dry.
Does cold weather affect infrared thermometer?
Do cold temperatures during winter affect readings? Yes, but please note that the operating temperature has to be between 10°C and 40°C (50°F and 104°F)! As long as the thermometer itself is outside this range no measurements can be performed.
Does an infrared thermometer work through glass?
The IR thermometer cannot measure internal temperatures. Do not take temperature measurement through glass. Glass has very distinctive reflection and transmission properties that do not allow accurate infrared temperature reading.
Is it illegal to have a mercury thermometer?
Those days have passed. Since 2001, 20 states have banned mercury “fever thermometers” for medical use, and regulations tighten every year. But as of today the federal government has more or less killed the mercury thermometer in the United States—NIST has announced it will no longer calibrate mercury thermometers.
