The LR-Cal PULSAR-80Cu dry well (metal block) 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 (well, 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.
The dry well temperature calibrator LR-Cal PULSAR-80Cu is available in two versions:
Without measuring inputs
Version with 2 measuring inputs
Both measuring inputs are suitable for resistance thermometer Pt 100 (2-, 3- or 4-wire) or Pt 1000, as well as for thermocouples (incl. cold junction compensation) types B, E, J, K, N, R, S and T.
The signal of connected probes can be displayed additionally in instruments display.
Extended scope of standard delivery:
Electr. cables, tools (plugs) for electr. connections
