Abstract
A refrigerant measuring device includes a casing, at least one sensor, and a detection circuit. The casing forms a plurality of coupling connector for selectively jointing sources of refrigerant to be detected to receive the refrigerant. The coupling connectors are connected to a channel to which the sensor is connected. The sensor includes an enclosure, a pressure detection circuit, and a thermocouple. The enclosure forms a connector to connect the channel and defines an interior chamber connected to the connector through a pressure-reducing neck that guides the refrigerant in a pressure-reduced condition into the chamber to contact the pressure detection chip and the thermocouple for detection of pressure and temperature of the refrigerant. The detection circuit receives the detected pressure and temperature from the sensor and also receives data of standardized reference pressure and temperature from a memory and display the detected pressure and the temperature and the reference data on a display.
