Frequently Asked Questions

What gases does the RKI 03 Series LEL monitor detect?

The 03 Series uses catalytic combustion sensing to detect combustible hydrocarbons in the 0–100% LEL range. It is calibrated for methane (CH4) and responds to a wide range of flammable vapors including propane, butane, and other hydrocarbons. For questions about a specific target gas, contact PK Safety at 800.829.9580.

What is the runtime difference between the NI-MH and alkaline versions?

The 72-0038 includes a NI-MH rechargeable pack and runs approximately 30 hours per charge. The alkaline variant (72-0037) delivers approximately 35 hours per set of batteries. The rechargeable option lowers long-term consumable costs in facilities where the monitor is used daily and a charging station is available.

At what LEL percentage do the alarms activate on the 03 Series monitor?

Factory defaults: first alarm at 10% LEL, second alarm at 50% LEL, OVER alarm at 100% LEL. Both user-adjustable setpoints let safety managers align the instrument to their site program. OSHA 29 CFR 1910.146 requires employers to evaluate and control flammable atmospheric hazards in permit-required confined spaces — many programs set action levels at or below 10% LEL.

Does PK Safety service and calibrate RKI 03 Series monitors?

PK Safety services RKI instruments in-house with factory-trained technicians, covering calibration, bump testing, sensor replacement, and repair for the full RKI portable line including the 03 Series. Calibration is recommended every 6 months or per your site safety program. Call our gas detection team at 800.829.9580 to schedule service or order calibration gas.

What does IP-67 protection mean for the 03 Series monitor in the field?

IP-67 indicates the monitor is fully dust-tight (rating 6) and can survive temporary immersion in up to 1 meter of water for 30 minutes (rating 7). This makes it suitable for wet industrial environments — water and wastewater plants, outdoor petrochemical sites, and construction — without requiring an additional protective housing.

What intrinsic safety certifications does the 72-0038 carry?

The 72-0038 carries ATEX/IECEx approval and CSA classification C/US as intrinsically safe for Class I, Division 1, Groups A, B, C, D hazardous locations (CSA pending at time of publication). These certifications confirm the monitor will not ignite flammable atmospheres under normal or single-fault conditions. Always verify the certification label on your specific unit before deploying in classified areas.
