The RITCHIE ENGINEERING 69385 is a replacement sensor filter designed for use with AccuProbe leak detectors. The filter protects the detector's sensing element from contaminants, oil mist, and debris that can degrade detection accuracy over time. Regular filter replacement is a standard part of maintaining reliable leak detection performance in refrigerant service work. This part is typically installed by licensed HVAC technicians and refrigeration service professionals as part of routine detector maintenance.
This sensor filter is intended for use in HVAC and refrigeration service applications where AccuProbe leak detectors are deployed. It is suited for both residential and light commercial service environments. Replacing the sensor filter on a scheduled basis helps maintain the sensitivity and accuracy of the detector, which is critical when locating refrigerant leaks in coils, line sets, fittings, and mechanical connections.
Designed for use with AccuProbe leak detectors.
Sensor filter replacement is performed by HVAC or refrigeration technicians as part of routine detector maintenance. Before replacing the filter, power off the leak detector and allow it to cool if recently used. Follow the detector manufacturer's replacement interval guidelines and handle the sensor tip carefully to avoid damage to the sensing element.
