HVAC Gauges Digital Manifold Gauge Set HVAC Dual Pressure&Temp Test 89 Refrigerant Gauges Digital R22/R134A/R410A Refrigerant Recharge Kit 3.5" LCD Display HVAC Manifold Vacuum AC Gauges

Product details

• 【Vacuum Pumping & Refrigerant Filling & Built-in 89 kinds of Refrigerant Database HVAC Manifold】Digital manifold gauges hvac can connect refrigeration equipment and vacuum pump for vacuum pumping operation. Vacuum pumping can make it easier to fill the refrigerant into the pipeline. Digital refrigerant gauges hvac 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..
• 【Warmly Note】Before using the HVAC gauges, 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..
• 【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..
• 【Evaporation/Condensation Pressure and Temp Test&High/Low-pressure Temperature Test】Digital manifold gauge set HVAC 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..
• 【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, hvac manifold gauge 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 is up to 3000 PSI..
• 【High Data Stability & Wide Application】Built-in 32-bit digital processing unit and high-precision data acquisition unit make it have high data stability. HVAC gauges use high-strength engineering plastics and a flexible non-slip silicone design, sturdy and durable. 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..
• 【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. Digital hvac gauges with hoses are 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..
• 【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..
