Liquid cryostat KRYO-VT-05-01 is designed to maintain the set temperature when determining the low-temperature characteristics of petroleum products in accordance with GOST 20287, GOST 5066, GOST 22254, GOST 18995.5, ASTM D97 (ISO 3016), ASTM D7346, ASTM D2386 (ISO 3013), ASTM D2500 and ASTM D6371.

  • 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.
  • The ability to regulate the temperature according to the program, consisting of 10 temperature-time intervals.
  • Selection of optimal settings depending on the heat carrier used.
  • Adjustable rate of heating and cooling of the coolant.
  • Possibility to connect an external temperature sensor.
  • 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.
  • Chiller power control.
  • Convenient built-in stopwatch for counting time when taking measurements.
