Description
Pre-calibrated hydrogen sensor module, 0–100% LEL
Some QEL products require a firmware selection or a serial number to identify the correct direct replacement. This is one of those products.
Please contact our team at (317) 788-6800 to purchase.
The QEL 85930-017-018 smart sensor makes it easy to keep your hydrogen gas detectors accurate without replacing the entire transmitter. This plug-in, factory-calibrated module drops into existing Q5, B5, Q6, or B6 hydrogen detectors, restoring 0–100% LEL performance with just a quick swap and power-up.
Instead of pulling down complete units or sending devices out for service, techs can change the sensor assembly in the field by removing a few screws, installing the new module, and verifying calibration. The replacement module uses the same catalytic bead hydrogen sensing technology as the original device, so you maintain consistent response in battery rooms, hydrogen storage areas, or other combustible-gas applications.
Key Features & Benefits
Keeps Existing Gas Detectors in Service
Designed specifically as a replacement for hydrogen channels in Q5/B5 and Q6/B6 transmitters, so you keep your installed hardware and simply refresh the sensing element.
Factory-Calibrated, Drop-In Module
Supplied as a pre-calibrated smart sensor assembly for Q5/B5/Q6/B6 devices maintenance is mostly mechanical: swap the module, power back up, and verify readings with test gas.
Accurate Hydrogen Monitoring up to 100% LEL
Matches the 0–100% LEL hydrogen range used by Q5/B5/Q6/B6 hydrogen transmitters, helping you maintain the same alarm points and ventilation strategy you originally commissioned.
Proven Catalytic Bead Sensing Technology
Uses catalytic bead technology for combustible hydrogen detection, the same approach specified for Q5/B5 hydrogen models, providing fast response and stable performance in industrial environments.
Supports Long-Term System Upkeep
Smart sensor assemblies are designed to be replaced periodically (typical life 2–3 years for combustible gas elements), helping you keep systems within spec over the life of a facility.
