Refrigerant Leak Detector – AS5750L

Fast and Reliable Refrigerant Leak Detection
The AS5750L Refrigerant Leak Detector is a portable and highly sensitive leak detection instrument designed for HVAC, air conditioning, refrigeration, and maintenance applications. Capable of detecting halogen-based refrigerants including CFCs, HCFCs, and HFCs, the AS5750L helps technicians quickly locate refrigerant leaks before they result in system inefficiencies, costly repairs, or environmental concerns.

Featuring adjustable sensitivity, visual LED leak indication, audible alarms, and a flexible stainless steel probe, the AS5750L enables fast and accurate leak detection even in hard-to-reach areas.

Features

  • Detects CFC, HCFC and HFC refrigerants
  • High sensitivity leak detection capability (<0.5 oz/year)
  • Instantaneous response for fast leak location
  • Flexible stainless steel probe for difficult access points
  • Adjustable sensitivity for different leak detection requirements
  • LED leak intensity indicator for relative leak size indication
  • Audible alarm with increasing alert frequency near leak sources
  • Rapid warm-up time of less than 20 seconds

Description

The AS5750L Refrigerant Leak Detector is designed to help HVAC technicians, refrigeration contractors, facility maintenance teams, and service engineers quickly identify refrigerant leaks in air-conditioning and refrigeration systems.

Using a highly sensitive sensor, the detector responds to halogen-based refrigerants commonly found in commercial and residential cooling equipment. The instrument can detect refrigerant leakage rates below 0.5 oz/year, allowing users to locate even small leaks before they develop into major system failures.

Its flexible stainless steel probe makes it easy to inspect confined spaces, evaporator coils, condensers, pipe joints, fittings, valves, and other difficult-to-access locations where refrigerant leaks frequently occur.

Detects Common Refrigerants
The AS5750L responds to a wide range of halogenated refrigerants, including:

  • CFC Refrigerants (R11, R12, R500, R503 and similar)
  • HCFC Refrigerants (R22, R123, R124, R502 and similar)
  • HFC Refrigerants (R134a, R404A, R125 and similar)

This makes the detector suitable for servicing various air-conditioning, refrigeration, cold storage, and cooling systems.

Designed for Field Service Applications

The detector features an adjustable sensitivity control that allows users to optimise leak detection performance based on the environment and leak size. LED indicators provide a visual representation of leak intensity, while the audible alarm increases in frequency as the probe approaches the leak source.

With a rapid warm-up time of less than 20 seconds and up to 9 hours of continuous operation, the AS5750L is well suited for daily field service work.

Key Applications

  • Air-conditioning system maintenance
  • HVAC servicing and troubleshooting
  • Refrigeration system leak detection
  • Cold room and cold storage inspection
  • Refrigerant recovery equipment maintenance
  • Commercial cooling system servicing
  • Facility maintenance and building services
  • Leak detection around compressors, valves and pipe joints
  • Refrigerant storage and recovery container inspection
