    Pressure test: gauge pressure Pressure test unit: Kpa; Mpa; bar; inHg; PSI. Pressure test range: 0 Kpa ~ 6000 Kpa Pressure test resolution: 1 Kpa Pressure test accuracy: +/- 0.5 %(FS)+ 5dgt Pressure overload limit: 10000 Kpa (10 Mpa; 100 bar;) Temperature test unit: °C (Celsius), °F (Fahrenheit) Temperature test range: -40°C~150°C (-40°F~302°F) Temperature test resolution: 0.1°C (-40°C~99.9°C), 1°C (100°C~150°C) 0.1°F (-40°F~99.9°F), 1°F (100°F~302°F) Temperature test accuracy: +/- 0.5 °C + 2dgt +/- 0.9 °F + 2dgt Vacuum test: relative vacuum Vacuum test unit: Kpa; Mpa; bar; inHg; PSI. Vacuum test range: -101 Kpa ~ 0 Kpa Vacuum test resolution: 1 Kpa Built-in 89 kinds of refrigerant NIST: According to American NIST standard Power Supply: 4pcs * 1.5V AA / LR6 batteries (Battery not included) Packing list: 1pc * HVAC Digital Refrigerant Gauge (Battery not included) 1pc * User Manual (in English) 2pcs * Temperature Clamps 3pcs * Refrigerant hoses 1pc * Suitcase 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. 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.

    Make sure this fits by entering your model number.
    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 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.
    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.
    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.
