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.
