RKI Calibration 4 Gas Mixture 58AL 81-0154RK-02
Description
The RKI Calibration 4-Gas Mixture (81-0154RK-02) delivers precise gas concentrations in a durable 58-liter aluminum cylinder — a mid-volume option that provides more calibration cycles per fill than the 34-liter variant while remaining manageable in size. This four-gas blend is designed for routine calibration of RKI confined space and sample-draw multi-gas monitors used in industrial safety 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

Frequently Asked Questions
How does the 58-liter cylinder compare to the 34-liter and 116-liter options?
The 81-0154RK-02 (58AL) is approximately 1.7x the volume of the 81-0154RK-04 (34AL), providing more cycles per fill. The 81-0154RK-116 (116AL) is the largest cylinder. The gas mixture is identical across all three sizes — choose based on fleet size and calibration frequency. Call 800.829.9580 for help sizing the right cylinder volume.
Is this the right gas for the SDM-3R calibration station?
Yes. The H2S 25 ppm / CO 50 ppm / CH4 50% LEL / O2 12% blend in the 81-0154RK-02 is compatible with the SDM-3R for GX-3R calibration. Use a demand flow regulator with the SDM-3R — not a constant flow regulator — so the station controls gas delivery. The SDM-3R Cal Station Bundle includes a compatible regulator.
Why is this calibration gas non-returnable?
Calibration gas is a hazardous material with a certified lot and concentration. Once shipped, it cannot be restocked or re-inspected. Verify the monitor model and sensor configuration before ordering. Call 800.829.9580 if there is any uncertainty about which gas mixture is correct.
What is the shelf life of this mixture?
H2S-containing calibration gas blends in aluminum cylinders typically have a shelf life of 12–18 months from the fill date. Check the cylinder label for the specific certification or expiration date at the time of receipt. Do not use expired calibration gas for compliance calibration — expired gas may not deliver accurate concentrations.
Does this gas require any special regulator?
Use a demand flow regulator when connecting to an automated calibration station such as the SDM-3R or SDM-Force. Use a constant flow regulator with gauge for manual calibration. The RKI demand flow regulator is sold separately and is compatible with this cylinder.
Can PK Safety service monitors that use this calibration gas?
Yes. PK Safety services the GX-3R, GX-3R Pro, GX-Force, and GX-6100 monitors in-house with factory-trained technicians. Call 800.829.9580 to arrange calibration, sensor replacement, or full repair service.
