This device is an essential professional tool for Air Conditioning and Refrigeration (HVAC) technicians. This integrated kit is used for the following purposes: [1, 2] Main Uses and Functions * Charging and Reading Refrigerant Gas: Measuring suction and discharge pressures and accurately checking gas levels for over 40 types of refrigerants (such as R410A, R22, R134a). * Leak and Vacuum Testing: Monitoring the evacuation of air and moisture from the system and detecting any leaks in the connections. * Temperature Measurement: Calculating Superheat and Subcooling rates thanks to the built-in temperature sensor and attached temperature clamp. [1, 2, 3, 4] Components of the case shown in the picture * Central Digital Gauge: Features a backlit LCD screen for clear digital readings. * Three Charging Hoses: Red (for high pressure), blue (for low pressure), and yellow (for service/charging and vacuum line). * Temperature Clamp Probe: Wraps around pipes to accurately measure the temperature of gas and liquid lines. * Quick Couplers: In blue and red, designed for car air conditioning systems. * Brass Adaptors: To change valve sizes to fit various devices.
