RKI Instruments H2S/CO/CH4 50% LEL/O2 116AL 81-0154RK-116
Description
The RKI Calibration Multi-Gas Mixture (81-0154RK-116) delivers precise gas concentrations in a durable aluminum 116-liter cylinder — the largest standard cylinder size in this product line, providing significantly more calibration cycles per fill than smaller 34-liter or 58-liter cylinders. This four-component blend is engineered for accurate calibration of multi-gas detectors used in confined space, industrial, and oil and gas applications.
Gas Mixture: H2S 25 ppm / CO 50 ppm / CH4 50% LEL / O2 12% in nitrogen
Note: This item ships via UPS Ground due to HazMat restrictions and is not available for expedited shipping. Calibration gas is not returnable. Please check your selection carefully before ordering.
Compatible with the following RKI monitors:
- RKI GX-3R
- RKI SDM-3R
- RKI GX-3R Pro
- RKI SDM-Force

Frequently Asked Questions
How many calibration cycles does a 116-liter cylinder provide?
The number of cycles depends on flow rate, hose length, and purge time per calibration. A 116-liter cylinder provides approximately 3x the cycles of a 34-liter cylinder at the same flow rate. For high-volume fleets running frequent bump tests and calibrations, the 116AL cylinder reduces cylinder change frequency and per-cycle gas cost. Call
800.829.9580 for help estimating cycles per cylinder for a specific fleet size.
Is the 81-0154RK-116 the same blend as the 81-0154RK-04 (34-liter)?
Yes. The gas mixture — H2S 25 ppm, CO 50 ppm, CH4 50% LEL, O2 12% in nitrogen — is identical. The only difference is cylinder volume: 116 liters vs. 34 liters. Both are compatible with the same RKI monitors and calibration stations. The
81-0154RK-04 is the 34-liter version.
Why is calibration gas shipped UPS Ground only?
Calibration gas cylinders are classified as hazardous materials under DOT regulations. Air carriers and expedited ground services do not accept them at standard rates. Plan for 3–6 business days transit time for UPS Ground delivery depending on the destination.
Can I use this gas with an SDM-3R automated calibration station?
Yes. The 81-0154RK-116 is compatible with the
SDM-3R calibration station. Use a demand flow regulator (not a constant flow regulator) with the SDM-3R so gas is only delivered when the station calls for it. This conserves cylinder contents and extends service life between cylinder replacements.
What is the shelf life or expiration date for this calibration gas?
RKI calibration gas cylinders carry a lot certification date. Shelf life for this blended mixture in an aluminum cylinder is typically 18–36 months from the fill date, depending on the constituent gases — H2S-containing mixtures have a shorter shelf life than LEL-only blends. Check the cylinder label for the specific expiration or use-by date at the time of receipt.
Can PK Safety service the monitors compatible with this gas?
Yes. PK Safety services the GX-3R, GX-3R Pro, GX-Force, GX-6100, and other compatible RKI monitors in-house with factory-trained technicians. Calibration, sensor replacement, and full repair are available. Call
800.829.9580 to arrange service or request a return authorization.
