Ultra precise calibration thermostat LOIP LT-920 is designed for calibration and adjustment of ASTM glass thermometers. This unit is state-of-the-art design and equipped with Carousel-type stainless steel rack. Rotating rack allows changing thermometers position in the testing chamber and enables very easy and comfortable observation during the test. Microprocessor PID thermo-regulator allows to set and monitor temperature, service parameters, thermo-sensor calibration data, performs current status, troubles diagnostic and low liquid level cut-out. Instrument can work with both water and non-aqueous fluids (silicon and other oils, glycol mixtures, etc.) as a heat medium. Thermometers are put in three-tier rack.

Features and benefits:

  • Carousel-type rack for 15 thermometers, rotating
  • Intelligent control system LOIP-ATC automatically adjusts PID-control parameters according to the fluid properties and eliminates influence of mains oscillations and ambient temperature instability
  • A high performance motorized stirrer ensures temperature uniformity throughout the bath
  • 5-digit LCD display for actual and set temperature, service parameters and codes
  • Accurate two-point calibration of temperature readings
  • In case of malfunction (e.g. due to low fluid level) auto-testing system stops the instrument and displays the causes
  • A stainless steel bath has glass observation port enables inspection during the test
  • Built-in cooling coil, when connected to tap water, permits operation at ambient or below ambient temperatures
  • A draining tap, installed in the bottom of the baths makes its refilling very simple.
