- The high accurate handheld device LR-Cal LRT 1000 is used as reference standard for tmeperature calibration purposes. 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/DKD certificate of calibration is included in standard delivery.
