• Evaporation/Condensation Pressure and Temp Test&High/Low-pressure Temperature Test HVAC Manifold The HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of 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 do. It also could test the temperature of the refrigerant in the high/low-pressure pipes.
• Superheat and Subcooling Test&Pressure Leak Test 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.
• Vacuum Pumping & Refrigerant Filling & Built-in 89 kinds of Refrigerant Database HVAC Manifold 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.

• How to Verify The Accuracy of The Temperature The temperature measured by the HVAC gauge is allowed to deviate by 3% from the actual temperature. There is a simple way to verify the accuracy of the temperature: Take out the black wire on the temperature clamp and put it in the boiling water. If the temperature is 100 degrees Celsius or the error is plus or minus 3%, it is normal.
• Note According to the current level of hardware processing in the industry, it is difficult to achieve a 100% completely sealed valve on the market. The sealing degree of our guage hardware can only reach 99%. But these slight leaks will not affect the use.
• Warmly Note Before using the HVAC guage, please make sure that refrigerant hoses and temperature sensor clamps are connected properly. Poor connection of the temperature sensor clamps will make it impossible to read the temperature. Poor connection of the refrigerant hoses will cause refrigerant leakage.

It has multi-functions such as phase sequence inspection, phaseloss judgment, short circuit search, voltage detection, live wire inspection, motor steering detection, etc. It is small in size and light in weight, and is a good helper for easy motor detection.
• Non-Contact Inductive Measurement The 3 phase rotation tester is different from the traditional phase sequence detection method,it adopts a clamp-shaped non-contact inductive measurement,and no need to open the wire, just clamp the three super-induction and high-insulation clamps on the insulation sheath of the three-phase live wire to detect the phase sequence,avoiding contact with the high-voltage bare live wire, which greatly improves the personal safety of the operator.
• Phase Sequence/Phaseloss Detection The non-contact phase sequence detector can detect the phase sequence status (positive phase sequence/negative phase sequence) of the three-phase power supply and judge the phaseloss. When the A, B and C phase indicators are all on, the R indicator light is on to indicate positive phase, the L indicator light is on for negative phase, and when any of the three phases is missing, the corresponding indicator light is not on.
• Live Wire Inspection & Line Maintenance The non-contact phase meter can detect whether the wire is live, clamp any one of the three-color induction clamps to the wire to be detected, if the wire under test is energized (in the live wire voltage setting Within the range of AC70~600V), the corresponding A, B, C phase indicator lights will be on. On the contrary, if the tested wire is lack of power, the A, B, and C phase indicator lights will not be on.
• Motor Steering Detection & Short Circuit Search The motor rotation indicator can detect the steering of the motor. Just place the meter on the motor and parallel to the motor rotation axis to test the steering of the motor. In addition, the phase meter can also judge whether there is a fault in the line, and quickly find the location of the disconnection, thus helping you to repair the line quickly and easily.
• Auto Shutdown Protection & Equipped With Easy-To-Carry Carrying Bag When the non-contact phase sequence detector is in idle state,the instrument will automatically shut down (automatically shut down after 5 minutes of no operation) to save power for you and prolong the life of the battery. In addition,the phase sequence detector is equipped with a high-quality black handbag,which can be put into the handbag after use,which is convenient for carrying and storage.
