Wireless Tunnel™ NIST2 sensors feature 2x NIST traceable, calibrated temperature sensors in a single stainless steel tube. Working as a pair they check each others values once a second for accuracy. If we deteect the sensors are out of acceptable tolerances an alert is sent warning that the sensor requires re-calibration. They work in pairs, with the averages of each pair averaged to give an overall reading. Improved accuracy and calibration checks with failover. Should any pair be out of calibration that value is ignored and an alert generated to warn that a pair is out of calibration.
