New Program Urges Consumers and Medical Professionals to Trade Up their Non-Contact Thermometers Toward an Accurate Temporal Artery Thermometer

| March 11, 2021

Non-contact thermometers still used widely for public screenings and in homes. The extensive evidence of their inaccuracies in detecting fever puts many people at risk of unknowingly transmitting COVID or delaying treatments.


Exergen Corporation, the maker of the #1 forehead thermometer sold nationwide and the only thermometer made in the United States, is providing an incentive for consumers and professionals to trade up their no-touch thermometers for an Exergen forehead thermometer. Since the pandemic hit, Exergen has conducted numerous campaigns to educate consumers and the medical community as to why non-contact thermometers are inaccurate compared to the Exergen thermometer, whose accuracy has been proven in more than 80 peer-reviewed published clinical studies.


There is a mounting body of scientific evidence proving that non-contact thermometers do not provide accurate temperature readings. A recent study in the American Journal of Infection Control compared the accuracy of no-touch thermometers to temporal artery thermometers and found that non-contact devices miss five out of six fevers. When body temperatures read below 99.5 degrees Fahrenheit, the thermometers showed similar results, but for temperatures above that, accuracy decreased substantially for the non-contact thermometer. When there is a fever, indicating the individual is sick and can transmit disease, the non-contact thermometer fails to reliably detect fever and provide protection for themselves or others.


Now, Exergen is making it easy for people to obtain an accurate thermometer by turning in their no-touch device to receive a rebate for purchasing a TemporalScanner. All they need to do is visit and upload a photo of the non-contact device they are trading in, the Exergen forehead thermometer they purchased, and their receipt. Once their request is processed, they will receive a $5 rebate. Medical professionals will receive a $20 rebate for each no-touch thermometer they trade up for an Exergen TAT-5000 professional model.

“Exergen’s mission is based on the fact that accuracy matters. As the #1 thermometer sold nationwide, we have a responsibility to ensure that anyone who wants an accurate thermometer can have one, especially during this time of uncertainty,” said Francesco Pompei, Ph.D., CEO of Exergen Corporation. “No-touch thermometers are largely used for show and can lull consumers and healthcare professionals into having a false sense of security. We are offering a sizable incentive through our trade-up program because nothing is more important than accuracy.”


Following the SARS outbreak in 2003, Exergen was invited to develop a scientific paper on the efficacy of the temporal artery thermometer compared to non-contact thermometers. The paper which was peer-reviewed and published in Proceedings of the SPIE presents the underlying science of how several physiological artifacts render no-touch measurements problematic, and how a successful method of non-invasive thermometry, TAT, overcomes them. The paper also examines the lack of supporting science behind no-touch thermometers. These devices measure the temperature at the outer surface of the forehead, which is not the same as the arterial temperature. Because they are simply pointed at the head, there is wide room for error by variations caused by ambient effects, skin emissivity, perspiration effects, and variable blood flow.


About Exergen Corporation

Exergen manufactures and markets two series of the TemporalScanner thermometer: a professional thermometer for hospitals and clinics, and a consumer at-home temporal thermometer sold in major retailers nationwide. More than two billion temperatures are taken each year with TemporalScanners. Used in thousands of hospitals and clinics across the country as well as in millions of homes, TemporalScanners are the #1 preference, nurses, pediatricians, and parents. The Exergen thermometer accuracy is supported by more than 80 peer-reviewed published studies covering all ages from preterm infants to geriatrics and all care areas from hospitals to homes.
