ASTM requires that if you are going to use an IR thermometer for measuring skin temperature, it must be accurate to within ± 0.3 °C (±0.54 °F). That is just to ensure that it’s good enough to detect if a person’s temperature is different than what it should be, or if they have a fever.
Hereof, are digital thermometers more accurate than infrared?
Research has shown that, when used correctly, infrared or no-contact thermometers are just as accurate as oral or rectal thermometers. No-contact thermometers are popular among pediatricians, as kids often squirm around when trying to get a temperature read, but it also holds true in mass temperature screenings.
One may also ask, can you use infrared thermometer on humans?
Yes. Infrared thermometers are capable of detecting the temperature of the human body. However, the device measures the surface temperature of the body. For clinical temperature measurement, you should use contact thermometers.
Does infrared have radiation?
Infrared (IR) is a type of electromagnetic radiation, including wavelengths between the 780 nm to 1000 μm.
A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.
The accuracy of an infrared thermometer can be checked using a comparator at any stable temperature. However, to reduce the possibility of a difference in temperature between the inside surface and the base test hole, it is more accurate at 22°C, ambient room temperature.
Just point the infrared thermometer gun, press the trigger and align the laser pointer on the object to get an almost instantaneous digital temperature. Infrared thermometers are an amazingly easily way to measure temperature.
Keep the device around 5 cm from the forehead to get accurate readings. Place the thermometers close to the area of measurements such as wrists or forehead. Ideally, maintain a gap of 5 cm between the two. Gently push the trigger and measure the temperature as shown on the LCD screen.
Distance: The primary use of infrared thermometers is in measuring the temperature of a subject from a distance. The device is beneficial in situations where it is difficult to reach the object to record the temperature.
The Hospital Grade No Contact Thermometer – Hammacher Schlemmer. This is the infrared thermometer used by hospitals for its convenient and hygienic operationthat provides an accurate temperature reading in only one second without touching the patient.
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. Your body temperature can vary depending on how active you are or the time of day. Generally, older people have lower body temperatures than younger people have.

Ford says doctors tend to rely on thermometers that read as close to the core body temperature as possible, noting that under-tongue thermometers tend to give the most accurate readings, and are used widely by doctors. However, Ford noted non-contact thermometers are also useful, especially during the pandemic.

No-touch or non-contact infrared thermometers measure temperature through the forehead from a close distance in seconds. They may be used on newborns and older people. They’re easy to use and may reduce the risk of spreading disease by allowing more physical distancing.
Digital thermometers are the most accurate way to measure body temperature. There are many types, including oral, rectal, and forehead, plus many that are multifunctional.
Differences between measurements can also result from the following factors: The thermometer is not the same temperature as the room you are measuring in (Example: it has been in a much warmer or colder room). The thermometer is inserted into the ear canal at a different depth or angle.
