LR-CAL,Germany Precision Reference Thermometer 0.005, For Laboratory, Model Name/Number: Lrt 1000

Precision Reference ThermometerModel LR-Cal LRT 1000 Accuracy ±0.005°C at 0°C (elsewhere ±0.02°C) as very high accurate reference for comparison temperature measurements Check and calibrate by means of comparison measurment TFT LCD, anti-glare colour display Capacitive touch screen, sratch-resistant Sampling rate 1 s Data recording (up to 200 data blocks or up to 3 h) Graphical analysis including standard deviation USB port for data transfer to PC software included DAkkS/DKD certificate of calibration included 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.
