All states and many companies are planning to reopen during COVID-19; non-contact temperature measurement devices will be used as part of the initial assessment for every individual at entry points to identify high temperature. Non-Contact Temperature Assessment Devices or Thermometer devices include quickly measuring and displaying a temperature reading from many different points of contact. Portable temperature measurement devices are especially useful when the patient’s body temperature varies from time to time.

Non-contact temperature sensor and thermal imager are non-contact temperature assessment devices use to measure individual temperature. Such devices are more in use nowadays. The latest temperature assessment devices are the flexibility in measurements and the ability to provide more detailed information. A raised temperature is a prominent way to identify a person who may have a COVID-19 infection. Be aware that even if you use the device correctly, it has minimal impact on reducing the spread of COVID-19.

Contact methods of body temperature measurement

There is a standard internal body assessment in which the sensor measures with direct skin contact. This assessment is generally exact because the measurement device is place around large blood vessels, reflecting the body’s core temperature. The most common spots for contact assessment are the armpit, anus and oral pit (mouth). Adequately long contact of the thermometer with the individual is an essential condition for an exact evaluation. Such temperature measurement is very time consuming, as it can require a few minutes, and it is done in direct contact with the patient or the inspected individual.

Benefits of Non-contact Temperature Measurement Devices

It is the most accurate way of measuring temperature. This way, human error can be minimized because there is no direct contact between the body and the thermometer. It is convenient to use since there is no need for a person to bend over to read the reading. It is easy to read because it displays a human-readable reading even with gloves on. In addition, it is economical because it only uses a tiny amount of electricity, unlike other types.

Limitations of Non-contact Temperature Measurement Devices

Non-contact thermometers cannot promise the accurate readings that other types of thermometers can provide. The accuracy of a human measurement can never be guaranteed because we are not able to control or measure infrared energy. Human temperature measurement relies on the ability of our skin to absorb infrared energy that reaches its deepest layers and passes through the body.

In Nutshell

The need to measure body temperature contactless and quickly during the COVID-19 pandemic emergency has led to the widespread use of infrared thermometers. Thermal imaging cameras, and thermal scanners to replace traditional contact clinical thermometers. However, the limits and issues of non-contact temperature measurement devices are not well known, and technical-scientific literature sometimes provides conflicting reference values on healthy subjects’ body and skin temperature. To limit the risk of contagion, national authorities have set the obligation to measure workers’ body temperature at the entrance to the workplace. A proper screening for body temperature measurement considering the role of uncertainty is essential to correctly choose the threshold temperature value and measurement method to access critical places during the COVID-19 pandemic emergency.
