Leak Detector for Refrigerants Unit UT336A — Sensitivity 3 g/yr, 6 Sensitivity Levels, Detects CFCs HCFCs HFCs

The Unit UT336A handheld leak detector for refrigerants is designed to locate leaks of CFCs, HCFCs and HFCs in HVACR and refrigeration systems. With a minimum sensitivity of 3 g/yr and six adjustable sensitivity levels, the instrument enables technicians to perform targeted inspections and quickly identify the source of escaping refrigerant. The compact, portable design and responsive sensor allow for close-proximity scanning of joints, valves and fittings to reduce refrigerant loss during repair work.

Advantages

The UT336A combines a low detection threshold with multiple sensitivity settings so users can balance speed and precision when searching for leaks. The detector responds rapidly to increases in refrigerant concentration and provides clear indication at different sensitivity levels, aiding accurate pinpointing. Its handheld form factor and intuitive controls make it suitable for field service and maintenance tasks where mobility and ease of use are important.

Suitable for

• Inspection and leak locating on air conditioning systems
• Refrigeration maintenance in commercial and industrial equipment
• Service checks during HVACR installation and commissioning
• Troubleshooting intermittent or slow refrigerant leaks
• Routine preventive maintenance to detect early-stage leaks

Key specifications

• Minimum sensitivity: 3 g/year
• Six adjustable sensitivity levels for targeted detection
• Detects gases: CFCs, HCFCs and HFCs
• Handheld, portable form factor for close-proximity scanning
• Rapid response sensor for real-time leak indication

How to use

Power on the detector and allow the sensor to warm up according to the manufacturer’s stabilization time. Select an appropriate sensitivity level for the expected leak size — use higher sensitivity for very small or slow leaks and lower sensitivity for faster detection of larger leaks. Move the probe slowly along potential leak points such as pipe joints, fittings, valves and access ports, keeping the probe tip close to the surfaces being inspected. Pause briefly at suspicious locations to confirm a consistent response before marking or repairing the leak source.

Usage recommendations

Use the lowest sensitivity level that still reliably indicates the leak to reduce false positives from background concentrations. Ensure proper sensor warm-up and periodic calibration as specified by the manufacturer for accurate readings. When inspecting systems under pressure, follow standard safety procedures and isolate electrical power where required.
