Introduction: It is a digital refrigerant meter which consists of high precision pressure sensor, digital temperature sensor and large scale integrated (LSI) circuit. As many as 36 refrigerant temperature parameters could be measured buy this meter. It is mainly used for the maintenance and service of the refrigeration system for its obvious advantages. The measurement of the pressure, condensation temperature and evaporation temperature of the refrigeration system are clear at a glance. The measurement of the pressure and temperature are accurate.     The features are as follows: 1.Large screen display of pressure and temperature. Observation could be made in multiple angles and the data are clear at a glance.   2.The instrument housing is durable as it is protected by rubber.   3.As many as 36 refrigerant parameters are available for a convenient use.   4.Micro power consumption design for a longer battery service life.   5.Various measurements such as the pressure of high and low ends, evaporation temperature, condensation temperature and the temperature of high and low pressure piping.   6.Calculation of the degree of overheating and the degree of supercooling.   7,Inspection for leakage of piping.   8,Examination of vacuum.
