Chauvin Arnoux launches its new CA 1900 thermal camera for instant detection of any abnormal fever.
"In an epidemic context, or simply to anticipate any health risk, it is increasingly recommended to monitor body temperature using a thermal camera. With the CA 1900 non-contact thermal camera, Chauvin Arnoux provides a simple, fast and practical response to easily and instantly detect whether employees or visitors are showing any abnormal fever".the company says.
Like an infrared thermometer, a thermal camera measures the surface temperature of a living being from a distance and without contact. Both capture the infrared radiation emitted (invisible to the human eye) by an individual to determine its temperature. The difference is that the non-contact thermometer will provide the temperature of a precise point, rather than a surface, as the thermal camera can do. What's more, an individual's temperature needs to be measured from a distance of 5 to 20 cm, whereas with an infrared body temperature camera, measurements can be taken from up to 1.5 meters away. This is reassuring for operators who measure the temperature of dozens of people every day.
Thermography is considered a practical and simple method for scanning both individuals and groups. The temperature is measured at the inner corner of the eye (more accurate) or at forehead level (more convenient) and an alarm is triggered if it is outside a temperature threshold set by the operator, or according to an average value of the temperatures measured on the six healthy people previously checked.
A quick temperature check
Because it's essential to ensure the smooth flow of people entering a production site, office building, public facility, airport, railway station or shopping mall, temperature measurement has to be very fast. The CA 1900 thermal camera takes the measurement in less than a second, and instantly displays the temperature value. With a temperature range of +30°C to +45°C, this infrared camera guarantees measurement accuracy of ± 0.5°C.
Contact-free and respecting the recommended distance of 1.5 meters between the operator and the person being tested, this device measures and displays the temperature of each individual in real time on the screen.
Body or skin temperature, the operator can adjust the value of the measured temperature to compensate for the difference between the two types of temperature. A cutaneous temperature reading, i.e. one taken at skin level, has a different value to that normally recorded with an auricular, rectal or buccal reading. While the average body temperature is between 37°C and 37.5°C, the skin temperature is lower, between 30 and 36°C for a surface area of 15 cm . We therefore need to adjust this range to obtain a more accurate "median" value.
To warn the operator of any abnormal rise in temperature, the CA 1900 infrared camera features two alarms, one audible, the other visual. The individual being monitored is thus immediately identified. A reassuring alarm for the person taking the measurement.
The standard tripod insert on the underside of the CA 1900 thermal camera enables rapid deployment, whatever the environment in which the device is to be installed.
Thanks to its long battery life, the CA 1900 infrared thermographic camera can operate continuously for up to 9 hours.
