The LR-Cal PULSAR-80Cu temperature calibrator is a compact instrument used to calibrate temperature probes, thermometers, thermostats and temperature mesuring sensors. The considerable size makes it suitable for calibrations of probes with large insertion lengths.
The LR-Cal PULSAR-80Cu temperature calibrator consists of a metal block (80 mm diameter x 300 mm depth) heated by a resistance which winds around the outer surface of the block. A hole with 60 mm diameter and 275 mm depth is made in the block for the apprpriate reduction inserts.
The LR-Cal PULSAR-80Cu is equipped with a counter-current forced air cooling system which keeps the temperature at the upper part of the well low. This system enables to check even very short probes, without heating the connecting head or the handgrip.
The instrument is equipped with a PID microprocessor controller with a resolution up to 0.01°C, allowing the setting of the standard of measurement to °C, °F or K and programming of ascent or descent ramps, and storage of thermostats' operative temperature.

Temperatur sensor calibration:
Automatic calibration routine for all type of temperature sensors with advanced features such reference sensor stabilization, time-calibration data are automatically populated and stored for printing report. This procedure can also be ran in manual mode to allow the operator to manually enter the data. This is particular useful when calibrating temperature device such as digital thermometer or analogue thermometers.
Simply set MAX and MIN value and the software will run an automatic stress test on single sensor or a batch.
Advance thermostat calibration:
Simply set the open and close temperature limits, type of thermostat, typ of test and the software will automatically run the test.
Indicated temperature ranges are valid at ambiemt temperature +20°C. The stated accuracy is based on ambient temperature +23°C and is guaranteed for 1 year.
To increase the measurement accuracy of the calibrator significantly, we recommend the -2I version of the temperature calibrator (with two measuring inputs) and the external high accurate reference probe LR-Cal LRT F.
