Digital Manifold Gauge Set for Air Conditioning/Refrigerator Digital Gauges HVAC with Double Pressure&Temp Test Manifold Digital, HVAC Gauges with Hose, Temperature Control Clip, Toolbox

Evaporation pressure and temperature test of manifold GaugeThe air pressure gauge 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.
The air pressure gauge can be filled with refrigerant through the visual window & Refrigerant type can be setBuilt-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.
High/Low-pressure temperature test & Pressure leakage test for HVAC toolsThe 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.
Product Description

Multifunctional Digital Manifold Gauge Set & 2 Years After-Sales Service

The Refrigeration Digital Manifold Gauge group instrument is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners, fridge and cold storage. The instrument has double pressure test, dual temperature test, digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. The instrument uses high-strength engineering plastics and flexible non-slip silicone design, the whole machine is solid and comfortable to hold. Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability.

Product Operation Steps:

1. Power on first, you need to install the battery, and then close the two valves.
Note: you need to press the ZERO key to clear the original reading first.

2. Connect the three-color hose, then open the valve, you can use it normally.

3. If the test is too cold or overheating, you need to set the corresponding refrigerant model, and you need to connect a temperature sensor (temperature clamp), the meter can automatically switch to read the overcooling or overheating degree.

After-Sales Service:

Our digital gauges HVAC provides 2 years after-sales service. DUOYI would like to make sure that you have the best experience possible. If you have any questions before purchasing or during the use of the product, please feel free to contact DUOYI, and our professional customer support team will provide assistance within 24 hours and promptly help you solve any problems or concerns you may encounter.
