- 【High/Low-Pressure Temperature Test & Pressure Leakage Test for HVAC gauges】The digita HVAC gauges can test the temperature of the digital refrigeration manifold in the high-pressure/low-pressure pipeline of the air-conditioning system. Pressure leakage test: Calculate the pressure difference between the initial test pressure and the second test pressure to determine whether the refrigerant leaks
- 【Evaporation Pressure and Temperature Test of Manifold Gauge】Digital manifold gauges HVAC can test the maximum pressure when the refrigerant changes from liquid to gas. The lowest temp when the liquid becomes gaseous.（The lower the pressure and temp of the evaporation are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do.）
- 【Digital Manifold Gauge Set】Digital manifold gauges are used to install, test and maintain refrigeration equipment (such as air conditioners, refrigerators and cold storage, etc.). Digital gauge has very powerful functions, such as: double pressure test, dual temperature test , digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. Equipped with two pairs of temperature control clips, which can be replaced at any time
- 【Condensing Pressure & Temp Test of Manifold Gauge】Digital manifold gauges HVAC can test the minimum pressure when the refrigerant changes from gas to liquid, and the maximum temp when the gas changes to liquid. (The lower the pressure and temp of condensation are, the higher the efficiency of the refrigeration cycle and the greater the refrigerant capacity will do.)

DUOYI

$129.00

More Details
Main highlights
- 【Vacuum Measurement & Pressure Leakge Test&High/Low Pressure Temp Test】Refrigerant meter vacuum table of the digital gauges hvac can be switched to each other.Vacuum test can test the percentage of vacuum measurement and vacuum pressure,can judge the air tightness of the pipeline.Calculate the pressure difference between the initial test pressure and the second test pressure, and observe whether there is any leakage in the refrigeration system pipeline,and can record the leakage time speed.
- 【V-Shaped Valve Switch&High-Precision Data】High/low pressure valve of the digital refrigerant gauges adopts a V-shaped design.Compared with the ordinary knob valve,the V-shaped valve is easier to control the amount of refrigerant filling,saving operation time,and Material is more durable.Built-in 32-bit digital processing unit and high-precision data acquisition unit,the data volume is high and stable.Pressure/temperature multi-unit automatic conversion (kPa,Mpa,bar,inHg,PSI,Celsius,Fahrenheit)
- 【Note】To ensure normal use, be sure to close the valve before each start or use, and then press ZERO to reset . When the value on the display is eliminated, then connect the three-color hose and then open the valve for use.
- 【Dual Pressure&Temp Test Of High/Low Pressure Pipelines】HVAC gauges can measure the pressure/temperature of the refrigerant in the high/low pressure pipelines of the air conditioner in real time.During the refrigerant pressure test,the meter can display the corresponding evaporation/condensation temperature.The smaller the deviation between the temperature measured by the temperature sensor and the evaporative condensation temp., the better the cooling effect and the quality of the refrigerant.
- 【Digital Manifold Gauge Set For 92 Refrigerants】Compared with other refrigerants meter,our digital manifold gauge can be filled with 92 types of refrigerants and has a wide range of applications.Meter have multiple functions such as dual pressure/temperature test,condensation evaporation pressure/temperature test,pressure leak test,vacuum degree test,calculation of supercooling/superheating.It is suitable for refrigeration equipment such as air conditioners, cold storages and refrigerators.
- 【Condensing/Evaporating Pressure And Temp Test&Supercooling/Superheating Test】During the refrigerant pressure test,it can automatically test the refrigerant condensation/evaporation pressure temp.The lower the condensation/evaporation pressure and temp, the better the cooling effect.The degree of supercooling/superheating is automatically read.The greater the degree of superheating,the less refrigerant is filling,the lower the degree of subcooling can improve the cooling capacity of the system.
- 【3.5" Backlit Display & Visual Refrigerant Filling Window & High Strength Material】HVAC digital manifold gauge set adopts 3.5-inch backlight display design,the data is easy to read,and each test result is divided by lines on the screen,the data is more intuitive.HVAC digital gauges is made of high-strength engineering plastic,with anti-slip design on both sides,which is comfortable to hold and durable.Meter has a visualization window through which you can keep an eye on the refrigerant filling.
