Wipcool Heated Diode Leak Detector

The WIPCOOL ALD-2 Heated Diode Leak Detector is a compact refrigerant leak detector designed for HVAC-R technicians working across air conditioning, refrigeration and heat pump systems. Using a heated diode gas sensor, the ALD-2 provides high sensitivity leak detection for common refrigerants with fast response and simple operation.

With a flexible 420 mm probe, LCD display, automatic/manual reset and minimum detectable leakage down to ≤3 g/year, the ALD-2 is a practical service tool for locating refrigerant leaks around pipework, coils, valves, fittings and service connections. It is suitable for CFC, HCFC, HFC, HC, and HFO refrigerants, making it useful for both legacy and modern HVAC-R systems.
