Thermostat for verification and calibration of P321 resistance measures
Instability and heterogeneity within ±0.05 °C
Temperature control range +15…+25 °C

Liquid thermostat TERMOTEST-20-01 is designed to maintain the set temperature during verification and calibration of P321 resistance measures .

  • Advanced self-diagnostics and protection systems for monitoring the excess of the coolant temperature over the set value, the coolant level in the bath, the temperature of the pump motor, the health of the heaters and their controls.
  • Turn on and off at the specified time thanks to the built-in clock.
  • Adaptive self-adjusting temperature controller.
  • Pumps made of stainless steel, bearings and spring couplings of the original design used in the drive guarantee long-term operation of thermostats with any coolant in a wide temperature range.
  • Possibility to connect an external temperature sensor.
