RKI Direct Connect Gas Sensor LEL, H2 Specific
Description
The RKI Direct Connect H2-Specific LEL Sensor provides targeted hydrogen detection for applications where hydrogen-specific discrimination is required. Unlike general-purpose LEL sensors, this sensor uses a catalytic element selected for hydrogen, delivering a fast 20-second response and a long 3–5 year service life. Explosion-proof with flame arrestors for use in Class I, Groups B, C, and D hazardous areas.
Compatible with Beacon 110, Beacon 200, and Beacon 410 controllers. Also see the LEL, CH4, and CO2 sensor and the O2, H2S, CO sensor.
Key Features:
- Electrochemical plug-in sensor — no tools required for replacement
- Hydrogen-specific catalytic detection
- Fast 20-second response time
- Compatible with Beacon 110, Beacon 200, and Beacon 410
- Indoor/outdoor rated
- Explosion-proof construction with flame arrestors
- Long sensor life (3–5 years typical)

Frequently Asked Questions
Why use an H2-specific LEL sensor instead of a general LEL sensor?
General-purpose LEL sensors are calibrated for one reference gas (often isobutylene or methane) and can read lower or higher for hydrogen due to its different thermal conductivity. An H2-specific sensor is optimized for hydrogen response, providing more accurate readings in hydrogen-only applications such as fuel cell facilities, battery charging rooms, and hydrogen storage areas.
What applications require H2-specific LEL detection?
H2-specific detection is commonly required in lead-acid battery charging areas, hydrogen fuel cell installations, electrolysis facilities, hydrogen storage and fueling stations, and any process that generates or uses hydrogen as a feedstock or byproduct.
What is the LEL for hydrogen, and what does OSHA require?
Hydrogen's lower explosive limit (LEL) is 4% by volume in air. Under 29 CFR 1910.1000 and NFPA 2, fixed detection systems with alarms at 10% LEL (action level) and 25% LEL (evacuation level) are commonly specified. Consult your industrial hygienist or fire protection engineer for your specific alarm set-point strategy.
How fast does this sensor respond to hydrogen?
The H2-specific Direct Connect sensor has a 20-second response time — faster than the 30-second response of the general-purpose LEL sensor — which is important in rapidly evolving hydrogen release scenarios.
How does PK Safety support RKI fixed H2 detection systems?
PK Safety services RKI Instruments fixed detection equipment in-house with factory-trained technicians. We can assist with sensor replacement, system calibration, and controller setup. Call 800.829.9580 for service or application support.
