Product introduction

The coolant pressure gauge is suitable for measuring the refrigerant pressure of medium or special medium with low temperature, such as air conditioning cabinet, chiller and cooling system.Refrigerant (refrigerant, snow seed) is also called refrigerant, which is the working medium of refrigeration cycle. The phase transformation of refrigerant is used to transfer heat, which absorbs heat when evaporating in evaporator, and releases heat when condensing in condenser. At present, there are more than 80 substances that can be used as refrigerant, the most commonly used are ammonia, freon, and a few hydrocarbons. A working fluid used in a freezing system to transfer heat energy to produce a freezing effect. According to the working mode, it can be classified into Primary and Secondary refrigerants. According to material properties, it can be divided into Natural refrigerant and Synthetic refrigerant, refrigerant pressure gauge, also known as snow seed gauge or freon meter, which is used to measure the pressure of various refrigerating systems in refrigeration system or equipment, such as air conditioning equipment, refrigerating system in cold storage, industrial chiller, cold coal filling equipment, central air conditioner, etc.Ordinary refrigerant pressure gauges are used to measure the positive and negative static pressure of a cold medium with no vibration or ripple effects suitable for measuring copper or copper alloys.Shock resistant refrigerant pressure gauges are used to measure the pressure of gases or liquids that are non-corrosive, non-explosive, non-crystalline, and non-precipitated to copper and copper alloys. The biggest characteristic of this product is that it can measure the pressure normally in the machine tool or equipment with severe vibration. The aseismic grades are V.H.4 and V.H.5, which are suitable for measuring the pressure of mechanical equipment in the places of intense vibration where medium pressure pulses are frequent and working for a long time.Does the refrigerant pressure gauge is suitable for stainless steel suitable for stainless steel components detection of strong corrosive medium and severe external corrosion environment without explosive precipitation and crystallization, the positive and negative pressure of gas or liquid medium, can be used in place of intense vibrations or medium pressure pulse frequent work environment, good generality, wide application, long service life. Stainless steel pressure gauges and shockproof pressure gauges can be used instead.Product specificationDIAMETER = BOTTOM CONNECTION = 2.6", LIQUID FILLED = 2.5"BACK CONNECTION = 2.5"CONNECTION = BOTTOM CONNECTION = 1/8" NPT, BACK CONNECTION = 7/16 "UNFPRESSURE RANGE = LOW PRESSURE = -76 cmHg ~0~250psi (15kg/cm2)HIGH PRESSURE = 0~500 psi (30 kg/cm2)MATERIAL = INTERNALS = PHOSPHOR BRONZE, banan.case AND BEZEL =NON - CORROSIVE STEEL OR SUS304ACCURACY = 1.5% F.S.Product advantagesFREON PRESSURE GAUGESMATERIAL AND WELDING METHOD USED CAN OBTAIN EXCELLENT wall-proof, impulse-proof AND VIBRATION PROOF CHARACTERISTICS.SUITABLE FOR AIR CONDITION SYSTEM R12,22,502,R134
