Review: Eliminates having to use multiple devices - You can accomplish the same using a standard manifold and a separate 2 channel thermometer, but you'll have to do the math for subcooling and superheating. Also, it can do pressure leak testing. I used it for the former, not the latter, and it works well.

## Features

- 【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.
- 【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.
- 【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.
- 【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)
- 【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.
- 【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.

You can accomplish the same using a standard manifold and a separate 2 channel thermometer, but you'll have to do the math for subcooling and superheating. Also, it can do pressure leak testing. I used it for the former, not the latter, and it works well.

### ⭐⭐⭐⭐⭐ Digital HVAC Guage that calculates Superheat and Subcooling
*by S***C on July 28, 2024*

This HVAC guage is not only a digital pressure gauge it also can measure temperature in two different locations. What I believe is the best feature is that if you are also measuring temperature the guage calculates Superheat and Subcooling real time. It does this automatically without having to fumble with charts, tables, a calculator or even use a separate divice to measure temperature. It allowed me to accurately add refrigerant to a refrigerator, that had lost charge through a slight leak over the years, using the preferred superheat method. To be fair I did not check the pressure accuracy of the guage. However, it is accurate enough for me and the above refrigerator is as cold as it was when new. Even the instruction booklet is clear. To get these features in a "Professional" digital guage would easily cost 3 times the price. I am totally happy with this purchase.
