Non contact thermometer enables users to measure temperature from a distance. It is specifically designed to safely take the body temperature of a person, regardless of room temperature. With its clear, backlit LCD display. It can accurately record body surface and forehead temperatures of infants and adults, without contacting the body.
Body temperature can be measured in a number of ways. Traditionally, body temperature has been measured using contact thermometers. That are placed on the forehead or in the mouth, ear, armpit or rectum.
Non-contact thermometers allow a person’s temperature to be taken with minimal (tympanic) or no (Non-contact infrared thermometer [NCIT], thermal scanner) contact with the person.
This means temperature can be measured without the discomfort of having to sit still with a thermometer in the mouth, armpit. Or rectum long enough to obtain a correct temperature reading.
The lack of contact also means the disinfection process between patients for the thermometers is minimal or unnecessary, allowing for easier and faster use when screening large numbers of people in settings like airports or border crossings.
The main types of these devices are non-contact infrared thermometers, tympanic thermometers, and thermal scanners. Non-contact infrared thermometers are held three to 15 cm away from the patient and typically measure temperature on the forehead or temple.
Tympanic thermometers measure the thermal radiation from the tympanic membrane and within the ear canal. Handheld thermal scanners can be used to take a person’s temperature from a greater distance than other thermometers, which may make them a good candidate for use in mass screening situations.
The optimal cut-off temperature for determining fever differs for each device. However, not everyone who has an infection or is infectious will have a fever. Additionally, fevers can be lowered by using antipyretic medications.
Non-contact temperature measurement is the preferred technique for small, moving, or inaccessible areas of the skin.
