Review: Similar to Testo 549. Good value for the money. Works great so far. Only negative is that the instruction manual isn’t very good, but HVAC techs using this equipment shouldn’t need a manual anyway. Good build quality. So nice to have superheat and sub cool calculated and displayed! Carry case and hoses were o.k. in quality too and hoses didn’t leak.
Review: Súper bien, lo utilice y cumplió con mis espectativas. Es básico pero muy funcional. Los tiempos de entregan los deben mejorar

## Features

- 【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.)
- 【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.）
- 【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
- 【The Digital Gauges HVAC Can Be Filled with Refrigerant Through the Visual Window & Refrigerant Type Can Be Set】Built-in 89 kinds of Refrigerant Database. Before filling the refrigerant, you can set different types of working refrigerants according to the filling requirements of the car. When filling the refrigerant, you can observe the filling state of the refrigerant through the visible window
- 【Built-In 32-Bit Digital Processing and Acquisition Unit & Large LCD Digital Display】Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Digital HVAC gauges also has a large-size liquid crystal display, supports LCD backlight, data display is clear and easy to read, and convenient to view various test data
- 【Refrigeration Digital Manifold Gauge】Digital manifold gauges HVAC uses high-strength engineering plastics and flexible non-slip silicone design and hook design, with Air Hose Manifold, Hose Clamp Set, Toolbox, easy to test and carry. Long-life valve switch, 1/4-inch standard interface design to ensure that the manifold Gauge durability, portability and versatility.The manometer for the installation, testing and maintenance of refrigeration equipment such as air conditioners,fridge and cold storage
- 【Automatic Multi-Unit Switching of Digital Manifold Gauge】Manifold Gauge has automatic multi-unit pressure conversion, Celsius/Fahrenheit temperature automatic conversion, including kPa, Mpa, bar, inHg, PSI, and temperature unit switching, which can meet the different needs of various tests. The HVAC gauges can also test the percentage of vacuum measurement and the leak time rate record
- 【NOTE】The battery is not included in the package！！！ It is normal that the test data and the actual data have an error within 3%. It is necessary to consider various factors such as the test environment and ensure the normal connection of the test line

*by A***R on 19 August 2025*

Yellow Vacuum/intake line has a leak at the joint. I emailed the company for a solution. No reply. I emailed them again and 3 days later I got a response back to contact Amazon for a replacement. I contacted Amazon and got a response back saying its past the 30 day return policy and that I need to contact the seller. Round and round we go. If you are going to sell some garbage, atleast do some quality controls and test it before it goes out the door.
