Johnson Controls RLD-H10-601R Replacement Sensor

The Johnson Controls RLD-H10-601R Replacement Sensor is a critical maintenance component designed for the RLD-H10 series refrigerant leak detectors, including the RLD-H10G-1, RLD-H10PM-1, and RLD-H10PRO models. Utilizing positive ion emission technology, this heated diode sensor provides the precision required to identify CFC, HCFC, and HFC refrigerants such as R22, R134a, R410a, and R404a. For technicians conducting leak verification, this sensor maintains high sensitivity levels—down to 0.006 oz/yr in stationary mode—ensuring compliance with SAE J2791 and J1627 standards. When your detector fails to respond to a calibrated leak vial even at maximum heater current, a sensor swap is necessary to restore HVAC leak detection accuracy. This OEM replacement part is engineered for a plug-and-play fit, allowing for rapid field servicing. Ensure the detector is powered down and the sensing head has cooled before installation to avoid thermal damage or injury. Regular replacement preserves the refrigerant gas detector bench-test performance in demanding commercial environments.

• Broad Refrigerant Compatibility: Accurately detects a wide range of halogenated gases and blends, including R-12, R-22, R-134a, R-404A, R-410A, R-502, and R-507.
• Advanced Sensing Technology: Employs a heated diode with alkali metal ionization for superior sensitivity compared to standard corona discharge sensors.
• High Precision Performance: Capable of detecting small leaks in high-background environments when used with manual balancing circuits.
• Direct OEM Fit: Specifically calibrated for Johnson Controls RLD-H10 series handheld units, ensuring seamless integration and reliable response times.

When should I replace the RLD-H10-601R sensor?
Replacement is required when the leak detector no longer triggers an alarm in the presence of a known leak source or a calibrated leak vial, even after the sensor heater adjustment on the bottom of the unit has been turned fully clockwise.

Is this sensor compatible with the older Bacharach H-10 units?
The RLD-H10-601R is designed for the Johnson Controls RLD-H10 series. While these units share a common heritage with certain H-10 platforms, you should verify your specific model number (e.g., RLD-H10G or RLD-H10PM) to ensure exact electrical and physical compatibility.

How can I extend the life of my replacement sensor?
Avoid exposing the sensor to high concentrations of refrigerant for extended periods, as this can "poison" the sensing element. Always ensure the probe filters (RLD-H10-602R) are clean to prevent moisture and dirt from reaching the heated diode.
