PRODUCT PARAMETERPRODUCT DETAILSBack Hook DesignTemperature Sensor InterfaceAnti-Slip Design Ball Valve Type SwitchObservation Window1/4 Inch Standard Interface Common Problems1、Low battery power supplyThe refrigerant gauge has low power sign. When it is displayed, it means the battery power is insufficient.

Once any damage is found, please replace it immediately.3、Failure of refrigerant fillingThere Is a valve core In the refrigerant inlet of the refrigeration system. When connecting the instrument, pay attention to the two terminals of the hoses. Connect one terminal with a core to the refrigeration system, while another terminal without a core to the refrigeration gauge.4、Potential leak pointsEvery hose terminal comes with a nylon pad limited to a certain life of use. Overuse or other situation will make it defective, which result in leakage.The instrument refrigerant inlet (the middle port of the Instrument ) has a port with a valve core, which is used to discharge the air in the connecting pipe by pressing the valve core after connecting the refrigerant source.5、Product does not work properlyPlease let us know and we can reship brand new gauge, hoses, temperature clamps or suitcase. -PAYMENT- -SHIPPING- -RETURNS–ABOUT US–CONTACT US–PAYMENT- 1.
