Replacement Sensor for RLD15

The UEI Test Instruments RLD15 replacement sensor is a heated solid electrolyte component designed specifically for the RLD15 leak detector. It restores the instrument’s ability to detect refrigerant leaks in HVAC and automotive air-conditioning systems. Technicians who rely on the RLD15 for daily diagnostics use this part to maintain factory-specified sensitivity.

Upgrading from a depleted sensor

A sensor should be replaced when the RLD15 no longer responds to known leaks or when its baseline reading drifts beyond calibration limits. The jump is worth it whenever the original heated electrolyte element has reached the end of its service life and the detector body remains in good working order.

Practical limits of heated electrolyte detection

Heated solid electrolyte sensors respond to halogenated refrigerants but can also trigger on certain solvents or cleaning agents present in the work area. They require a warm-up period before each use and their sensitivity gradually declines with cumulative exposure, so periodic verification against a calibrated reference leak is necessary.
