Refrigerant Leak Detectors for HVAC and refrigeration maintenance, designed to identify refrigerant gas leaks in air-conditioning and cooling systems. A Refrigerant Leak Detector is used to locate refrigerant gas leaks in air-conditioning, refrigeration and HVAC systems. These instruments help technicians identify leaks around pipes, joints, compressors, condensers and evaporators. Testo 316-3, for example, uses a heated-diode sensor and provides adjustable sensitivity and automatic zeroing. #RefrigerantLeakDetector #GasLeakDetector #HVACTools #RefrigerationTools #HVACMaintenance #RefrigerantTesting #Testo #KusamMeco #AAGAMCorporation
