RKI Calibration 4 Gas Mixture 81-0154RK-04
Description
Need it Sooner?
We recommend the
PK Safety RKI Equivalent 4 Gas Calibration Gas Mix 34 Liter as a great substitute that is available and ready to ship.
The RKI Calibration 4 Gas Mixture 81-0154RK-04 is the OEM-specified calibration gas for RKI 4-gas portable monitors including the
GX-Force and
GX-3R family. Each 34-liter aluminum cylinder is filled with 25 ppm H₂S / 50 ppm CO / 50% LEL CH₄ / 12% O₂ in nitrogen — the four-gas blend required to bump test and fully calibrate instruments measuring the standard confined space hazards. Calibrating every six months and bump testing before each use day keeps your gas monitor OSHA-compliant and life-safety ready.
Note: This item ships via UPS Ground due to HazMat restrictions and isn't available for expedited shipping. Calibration gas is not returnable. Please check your selection carefully before ordering.
Compatible with the following RKI gas monitors:
- RKI GX-2009
- RKI GX-2012
- RKI GX-3R
- RKI GX-3R Pro
- RKI GX-Force

Frequently Asked Questions
Which RKI monitors is the 81-0154RK-04 calibration gas compatible with?
This calibration gas mixture is compatible with the
RKI GX-Force,
RKI GX-3R,
RKI GX-3R Pro, RKI GX-2009, and RKI GX-2012. It is the standard four-gas mixture for RKI instruments that monitor LEL combustibles, oxygen, carbon monoxide, and hydrogen sulfide simultaneously.
Why does this calibration gas ship via UPS Ground only?
Compressed gas cylinders are classified as hazardous materials under DOT regulations, restricting them to ground transport only. Expedited air shipping is not available. The calibration gas is also non-returnable, so verify the gas mixture, cylinder size, and compatible instruments before ordering. Contact PK Safety at
800.829.9580 with any questions before placing your order.
How many calibrations does a 34-liter cylinder provide?
A 34-liter aluminum cylinder provides enough gas for approximately 10–20 full calibrations depending on flow rate, hose length, and instrument purge requirements. Bump tests use considerably less gas per test. For high-frequency or multi-instrument calibration programs, consider a 58-liter cylinder or an automated station such as the RKI SDM-Force Calibration Station, which connects up to three cylinders simultaneously.
How often should I calibrate my RKI GX-Force or GX-3R?
RKI recommends a bump test (functional response check) before each day of use and a full calibration at minimum every six months. High-exposure environments, sensor replacement, or repeated bump test failures all require an immediate full calibration. The RKI SDM-Force automates this record-keeping for
GX-Force fleets.
Do I need a regulator to use this calibration gas cylinder?
Yes. A demand flow regulator is required to connect the 34-liter cylinder to your instrument's calibration port. The RKI Calibration Gas Demand Flow Regulator (available separately) is compatible with 34 AL cylinders. Alternatively, the GX-Force Confined Space Kit (72-FA-A-A10-51) includes the cylinder, regulator, and tubing as a complete bundle.
