‎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 (e.g., 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 integrated temperature sensor and connected thermal clamp. [1, 2, 3, 4] ‎Components of the Kit Shown in the Image * Central Digital Gauge: Features a backlit LCD screen for clear digital readings. * Triple Charging Hoses: Red (high pressure), blue (low pressure), and yellow (for service/charging and vacuum line). * Clamp Temperature Probe: Wraps around pipes to accurately measure the temperature of gas and liquid lines. * Quick Couplers: Blue and red, designed for car air conditioning systems. * Brass Adaptors: To change valve sizes to fit various devices.
