Precise leak detection Uses advanced sensing technology and microprocessorbased circuitry to accurately identify leakage points for refrigerants including CFCs, HFCs, and HCFCs. Supports effective troubleshooting of HVAC systems by locating leaks quickly and reliably. Provides reliable detection across a wide range of refrigerants to aid in diagnosis and servicing. Adjustable sensitivity Features adjustable sensitivity with intuitive clockwise/counterclockwise control. Turn clockwise for sensitivity to detect small leaks; turn counterclockwise for broader scans during inspections. Allows tailoring to different environments and leak sizes, helping reduce false positives and improve efficiency. Leak alarm system When a leak is detected, the audible alarm intensifies to a sirenlike sound that corresponds to the concentration of gas detected. A flashing indicator light provides visual confirmation of detected gas levels. Delivers clear, immediate notification to onsite personnel for prompt investigation and action. 23 use scenarios Scenario 1: Residential HVAC service with suspected refrigerant leakage. Use the detector to pinpoint leak points around connections and coils, enabling precise prompts and reduced service time. Scenario 2: Commercial rooftop system inspection. Use sensitivity setting to identify small leaks first, then switch to broader scans to map larger leak areas during routine maintenance. Scenario 3: Post verification in a workshop. After repairs, use the detector to confirm the absence of residual leaks before recharging the system and commissioning it.
