BUILT-IN 92 TYPES OF REFRIGERANTS NIST

Capable of switching between common refrigerants, making it ideal for diverse maintenance scenarios and intelligent diagnostic system failures.

LEAKAGE TIME & SPEED RECORD

Convenient operation, direct reading of process data.

EVAPORATION/CONDENSATION TEMPERATURE DISPLAY

The greater the subcooling, the better the refrigeration capacity of the refrigeration system. Greater superheat indicates a reduced opening of the expansion valve, potentially due to insufficient refrigerant charge.
