High data stability wide application hvac gaugebuiltin 32bit digital processing unit and highprecision data acquisition unit make it have high data stability It uses highstrength engineering plastics and a flexible nonslip 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 Nonslip silicone design hook design refrigerant hoses temperature sensor clampssilicone nonslip 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 temperaturethe 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
Superheat and subcooling testpressure leak testwhen refrigerant type is set and temperature clamps are connected to air conditioning pipes hvac gauges automatically read the degree of superheatsh and subcoolingsc 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
Refrigerant observation window large lcd digital display multiple unit switchingwhen 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 celsiusfahrenheit
Noteaccording 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
Evaporationcondensation pressure and temp testhighlowpressure temperature test hvac manifoldthe 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 evaporationevcondensationco 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 highlowpressure pipes
Vacuum pumping refrigerant filling builtin 89 kinds of refrigerant database hvac manifolddigital 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 builtin 89 kinds of refrigerant pressuretemperature database Before you fill refrigerant you can set different types of working refrigerants according to the car needs to fill
Warmly notebefore 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
