Exergen's self powered micro IRT/C's are the most reliable non-contact temperature sensors in the market place. There are no active electronics so these passive thermocouple sensors can not fail.
Patented technology, the principals of operation of Exergen's sensors are calibrated to match conventional thermocouples at a specific temperature. By adjusting the calibration setting (c) of the IRT/C to equal the Seebeck coefficient (a), the signal output (mVout) will be within 2% linear to match the conventional thermocouple at a temperature close to the calibration point. As a result, when the Exergen IRT/C is wired into a conventional t/c input device, the target temperature (Tt) displayed will be the same as the surface (Ts).
IRt/c’s are pre-calibrated at the factory for typical target material emissive properties, but actual emissivities may differ. The accuracies specified assume that the precalibrated value is correct for your installation, or that the system has been calibrated at a single point for the application.

Since the outbreak of the Covid-19 pandemic, we have received a lot of interest in the use of our infrared temperature sensors for body temperature measurement. Our sensors are designed for industrial and laboratory surface temperature measurement. They are not designed or certified for body temperature measurement or for medical use. Because of this IOThifty does not warranty or guarantee their use in body temperature measurement applications
