Digital Manifold Gauge Set Pressure&Temp Test HVAC Manifold Pressure Leak Test Digital Refrigerant Gauges Vacuum HVAC Gauges with Refrigerant Hoses&Temperature Clamps&Lcd Display for Air Conditioning. 14.02 x 11.89 x 4.57 inches; 6.19 Pounds. 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. Before you fill refrigerant, you can set different types of working refrigerants according to the car needs to fill. Refrigerant Observation Window & Large LCD Digital Display & Multiple Unit Switching? 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. High Data Stability & Wide Application HVAC Gauge? 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. Non-slip Silicone Design & Hook Design & Refrigerant Hoses & Temperature Sensor Clamps? Silicone non-slip design can prevent slip and fall so that you can easily work without gloves. Equipped with a hook that allows you to hang the gauge on the car without holding it all the time.
Besides, it is equipped with refrigerant hoses and temperature sensor clamps for better use. Connect the temperature clamp to measure the temperature. The burst pressure of the hose set is 3000 PSI. 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. 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.
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. How to verify the accuracy of the temperature? The temperature measured by the gauge is allowed to deviate by.
NOTE: Please pay attention to temperature unit conversion between Celsius/Fahrenheit. Why does the pressure value fluctuate slightly? Is it a leak or is the data inaccurate? According to the current level of hardware processing in the industry, it is difficult to achieve a 100% completely sealed valve on the market.Does this gauge have a micron reading function? No, the accuracy of this refrigerant manifold gauge can only reach the accuracy equivalent to this unit: -101 Kpa-0 Kpa. The HVAC guage will read random numbers when it is powered on.
Key to clear the numbers after you power it on, and then you can use it normally (It is not correct to use it directly without pressing the ZERO button). Before using the HVAC guage, please make sure that refrigerant hoses and temperature sensor clamps are connected properly. Power it on, then close the two valves, press the ZERO key to clear the reading. Connect the three-color hoses, then open the valve, and use it normally.Regarding the evaporation temperature, the condensing temperature is explained as follows. Evaporating temperature: The lower the evaporating temperature, the lower the evaporating pressure and the refrigeration coefficient of the system. In this case, the load of the system continues to increase, which causes the energy consumption of the system to continue to increase. Pressure test unit: Kpa; Mpa; bar; inHg; PSI.

Refrigerant hoses connection and valve operation method of Vacuum Test. Close blue valve tightly and do not connect any hoses to the corresponding inlet.Connect the vacuum pump to the vacuum pump inlet of the refrigerant gauge with the yellow hose. Open the red valve, connect the device under test with the corresponding red hose, and then you can start the vacuum operation. Note: In the vacuum operation, the blue valve does not work, only the red valve does.
The blue valve needs to be closed. If the blue valve is not closed, the air pressure will escape from the blue valve and cause a leak, and the test data will be inaccurate.
