Can the Wrong Temperature Screening Device Lead to a COVID Outbreak In Your School?

As temperatures drop this Winter, so will the accuracy of your ordinary, non-contact thermometer.

Can the Wrong Temperature Screening Device Lead to a COVID Outbreak In Your School?

FeverWarn is the only temperature sensing system that works in cold weather, hot weather, or direct sunlight.

Traditional non-contact infrared thermometers are notorious for providing wildly inaccurate readings. Accuracy is so important in school temperature screenings because an inaccurate reading could lead to a feverish student being cleared through a temperature scan that then infects the rest of the school. These ordinary IR thermometers are notoriously inaccurate for two science-based reasons:

First, traditional infrared thermometers are susceptible to the surrounding (ambient) temperature or environment in which the scan is being done and can therefore yield inaccurate results. These traditional, non-contact thermometers are especially affected on warm summer or cool winter days, or when there is an abundance of sunlight. The infrared sensor on these thermometers is easily affected by direct sunlight as well as hot or cold air molecules.

In a recent Walter Reed presentation, Dr Fauci cited a trip to the White House on a hot weather workday when his temperature was registered by a handheld non-contact thermometer at 103°F outside of the White House, 97.4°F in an air-conditioned car, and then 93°F at another facility. That’s a 10°-degree variation in a few hours!

Secondly, most ordinary infrared thermometers can only operate when the surrounding ambient temperature is at or above 64° F or at or below 90° F degrees. This means that a temperature check during cold winter days, warm summer days, or in a highly air-conditioned or heated environment may not yield accurate readings or might not even work at all.

Only FeverWarn includes its proprietary OPX technology in all its temperature scanners. This game-changing technology extends the temperature bandwidth of its non-contact scanners by up to 50% over traditional non-contact thermometers. OPX technology consists of new spatial geometry sensors combined with artificial intelligence software to filter out the effects of hot and cold weather as well as problems with direct sunlight.

Unlike any other non-contact thermometer or temperature scanner on the market, FeverWarn can provide ultra-high accuracy in environments as cold as 40°F all the way up to as hot as 104°F, rendering all other non-contact thermometers obsolete.Currently, FeverWarn’s touchless, self-service, HIPAA-compliant temperature scanners are being used by thousands of American schools, preschools and childcare centers, medical clinics, hospitals, urgent care centers, and other organizations who need to accurately temperature check large volumes of guests, patients, students, and employees.

Now, as schools across America plan and implement their infection-prevention protocols for the 2022 school year, FeverWarn’s high-accuracy, high volume, portable temperature scanners aim to provide schools with an affordable solution to temperature check their students accurately and safely.

  1. When are we going to recognize that Asymptomatic people with COVID-19 do not necessarily show an unusual temperature?… They appear to be “normal” but they can be “carriers” and make up as much as 35% of your “guests”. It depends on age and background/associations etc. Even if that number is high and it is only 20% …….is that reasonable? Let’s not kid ourselves …..we need a better way to screen than just “temperature” – unfortunately – there is not currently one on the markets that can get any reasonable throughput.

  2. Non-contact thermometers are not as accurate as contact thermometers, in any environment. The ambient air temperature will affect the thermometer. Take the temperature of someone twice, from the same distance, with the same parameters and chances are you will get different results. Even oral thermometers aren’t always consistently accurate. Only way to get an accurate reading is rectally, and you’re just not going to get folks to “stand still” for that.
