About product                                                                          

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.

Features 

• Large screen display of pressure and temperature. Observation could be made in multiple angles and the data are clear at a glance.
• The instrument housing is durable as it is protected by rubber.
• As many as 36 refrigerant parameters are available for a convenient use.
• Micro power consumption design for a longer battery service life.
• Various measurements such as the pressure of high and low ends, evaporation temperature, condensation temperature and the temperature of high and low pressure piping.
• Calculation of the degree of overheating and the degree of supercooling.
• Inspection for leakage of piping.
• Examination of vacuum.

Operating

     After the desired operating condition is set well and the instrument is connected with the related piping and equipment, the digital refrigerant meter could be put into operation. Connect the instrument with the refrigeration equipment. Turn on the instrument and the meter will enter the operator’s last completed operating interface automatically. Push down the desired buttons and observe the refrigeration equipment pressure, the evaporation temperature, the condensation temperature, the measured temperature of the high pressure end, the measured temperature of the low pressure end, the degree of overheating and the degree of supercooling. Also, it will inspect the equipment for any leakage.

Cautions

      Two outside temperature sensors are required in the observation of the degree of overheating and the degree of supercooling.

Aintenance and Service of Instrument

• When the instrument does not use for a long time, it should take out the batteries to prevent the meter from damage.
• When the instrument does not use, the connection thread should be capped to prevent the thread from damage.
• The instrument is not suitable to any corrosive liquid, especially, ammonia and any ammoniated refrigerant.
• Never open or close the valve with sudden force to prevent the sealing element from damage.
• The hose is a wearing part. Check the hose for its aging condition and replace it promptly.
• It is recommended to check the sealing condition of the instrument periodically.
• Always store the instrument in a dry place to prevent it from moistu

  How to use

• Selection of Refrigerant

• Setting Unit of Pressure and Unit of Temperature

• Setting Local Atmospheric Pressure
