High-precision reference measurement standard for industrial temperature calibrations. The highly precise temperature probe of the hand held device XP101 is an ideal reference standard e.g. in calibration laboratories. It´s Mini USB interface uncludes software and online data collection. Excellent stability through multiple annealing cycles. Sensor characteristic curve is determined individually and is saved in the device. Integrated root 2 function for determination of the sensor self-heating, plus automatic elimination of parasitic thermovoltage. For traceability to national standards a DAkkS calibration certificate is attached.
