2. Product features:

The main functions of the system include:

Display and record specimen center temperature and circulating liquid temperature;

Freeze-thaw process conversion and circulating liquid temperature control;

Number of freeze-thaw cycles control;

Compressor exhaust pressure, suction pressure and motor unit temperature rise protection;

Circulating liquid flow protection and over temperature protection;

Motor overload protection, etc.

The whole freeze-thaw test process is completely automatic, photoelectric alarm is given in case of failure, and corresponding protection is taken by itself.

The equipment adopts the internal and external machine separation layout, the cooling and heating and circulating pump are placed outdoors, and the test box and control system are placed indoors, which effectively solves the problem of high temperature and noise in the test room caused by the integrated machine.
