Our digital HVAC manifold gauge set also features Bluetooth connectivity, allowing you to easily connect the gauges to your smartphone or tablet for remote monitoring and data logging. This added convenience enhances the functionality of the gauges and provides you with even more flexibility in your HVAC maintenance tasks.

In addition, the HVAC gauges can also perform dual pressure and temperature tests to help you determine the refrigeration capacity of the refrigeration system. The lower the pressure and temperature of the evaporation (Ev)/condensation (Co) are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will be. It can also test the temperature of the refrigerant in the high/low-pressure pipes.

When refrigerant type is set and temperature clamps are connected to air conditioning pipes, HVAC gauges automatically read the degree of Superheat(SH) and Subcooling(SC). The higher the degree of superheat, the smaller the opening of the expansion valve (the refrigerant filling is less) can be determined. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.

Digital manifold gauge set can connect refrigeration equipment and vacuum pump for vacuum pumping operation. Vacuum pumping can make it easier to fill the refrigerant into the pipeline. HVAC gauges is built-in 89 kinds of refrigerant pressure&temperature database. Before you fill refrigerant, you can set different types of working refrigerants according to the car needs to fill.

When filling the refrigerant, you can observe the filling status of the refrigerant through the visible window. Equipped with large LCD display, clear data display and easy to read. You also can switch multiple pressure units, including kPa, Mpa, bar, inHg, PSI, along with the temperature unit switch between Celsius/Fahrenheit.

Built-in 32-bit digital processing unit and high-precision data acquisition unit make it have high data stability. It uses high-strength engineering plastics and a flexible non-slip silicone design, sturdy and durable. Digital refrigerant Gauge is an auxiliary instrument for the installation, testing and maintenance of refrigeration machines such as automobile air conditioner, household air conditioning, refrigeration equipment and cold storage.
