RKI PS 2 Combustible Single Point Stand Alone Monitor
Description
RKI PS-2 Combustible Single Point Stand Alone Monitor is a cost-effective solution for hydrogen detection in battery rooms, or for LEL-level detection of a variety of flammable or solvent vapors in general industry.
The PS-2 is a multipurpose gas monitor utilizing a MOS (metal oxide sensor) for long-lasting, low-maintenance detection of LEL levels of many gases or vapors.
The PS-2 has two alarm levels for increasing gas or vapor levels. Each alarm level activates a 12-amp relay inside the unit, and terminals are provided for wiring the relay to activate an external alarm device or ventilation fan. Contact the factory to confirm your specific gas detection requirement before ordering.
Applications: Battery storage locations, Petrochemical plants, Refineries, Water & wastewater treatment plants, Degreasers, Gas, telephone & electric utilities, Manufacturing facilities, Steel, Automotive, HVAC
Key Features:
- LEL detection available for many gases
- Two alarm levels
- Stand-alone system — operates independently
- Input voltages: 24 VDC standard, 115 VAC or 48 VDC (optional)
- Audible and visual alarms
- Compact design
- Simple installation
- AC version equipped with power cord
- Relay contacts rated 12A @ 115 VAC
- Low maintenance
*Inquire about adding calibration kits with the monitor.

Frequently Asked Questions
What is a metal oxide sensor (MOS) and how does it detect combustible gases?
A metal oxide sensor (MOS) works by measuring changes in the electrical resistance of a heated metal oxide semiconductor material as combustible gases adsorb to its surface. When flammable vapor contacts the sensing element, resistance drops and the monitor generates an alarm signal. MOS sensors are particularly well-suited for detecting hydrogen gas and a wide range of hydrocarbon vapors at LEL concentrations, and they have a long operating life with minimal maintenance requirements compared to catalytic bead sensors in some environments.
What environments is the RKI PS-2 designed for?
The PS-2 targets locations where a low-cost, single-point fixed LEL monitor provides value: battery charging rooms (forklift, UPS, standby battery banks), petroleum storage and dispensing areas, refinery perimeters, water and wastewater pump stations, utility vaults, and manufacturing facilities where solvents or flammable vapors may accumulate. Its compact, wall-mount design simplifies installation in space-constrained locations. See our full fixed gas detectors collection for multi-channel options.
How does the PS-2 relay output work to control external devices?
Each of the PS-2’s two alarm levels drives a dedicated 12-amp relay rated at 115 VAC. The relay contacts can wire directly to an external audible alarm horn, a strobe light, or a ventilation fan contactor. This lets facilities automate a response — activating forced ventilation when the first alarm triggers — without a separate controller. Wiring terminals are accessible inside the unit; follow NEC Article 501 requirements for classified location wiring.
Does PK Safety service or calibrate the RKI PS-2 monitor?
PK Safety services RKI instruments in-house with factory-trained technicians, including fixed combustible gas monitors like the PS-2. We provide calibration verification, sensor evaluation, and repair services. MOS sensors have a long operating life, but periodic calibration checks confirm the monitor is responding correctly to the target gas. Call PK Safety at 800.829.9580 to discuss service intervals and calibration gas for your specific application.
Can the PS-2 detect hydrogen gas in battery storage rooms?
Yes — the PS-2 with MOS sensing is well-suited for hydrogen detection in battery rooms. Lead-acid batteries off-gas hydrogen during charging, and MOS sensors respond effectively to hydrogen at LEL concentrations. OSHA’s general industry ventilation standards and the NFPA 70 National Electrical Code have specific requirements for battery room ventilation. The PS-2’s relay output allows it to directly control a ventilation fan, automating the response when hydrogen accumulation is detected. Contact PK Safety at 800.829.9580 for application guidance.
What power options are available for the RKI PS-2?
The PS-2 is available in a 24 VDC version (73-1020RK-01) and a 115 VAC version (73-1021RK-01). The 115 VAC model ships with a 6-foot power cord for direct outlet connection. A 48 VDC input option is also available by special order — contact PK Safety at 800.829.9580 to inquire about this configuration.
