Frequently Asked Questions
Why does O2 calibration use nitrogen (N2) instead of an oxygen mixture?
O2 calibration for deficiency detection uses a two-point method. Fresh air (approximately 20.9% O2) provides the span reference point. Pure nitrogen (0% O2) provides the zero reference, allowing the monitor to establish the full detection range. The 34AL cylinder of 100% N2 in this kit supplies the zero-gas reference. The OX-04 operator manual details the complete calibration procedure.
Is this kit compatible with OX-04 models other than the 72-0018?
This kit is designed for the
OX-04 Series O2 Single Gas Monitor. If there is uncertainty about whether a specific OX-04 variant is compatible with this calibration procedure, call
800.829.9580 and reference the monitor's part number for confirmation.
How often should the OX-04 be calibrated?
RKI recommends bump testing before each shift and full calibration per the site's safety program. For confined space work under OSHA 29 CFR 1910.146, the O2 monitor must be in known-good calibration before entry into any permit-required confined space. The OSHA PEL for oxygen-deficient atmospheres is below 19.5% O2 per 29 CFR 1910.146 — calibration ensures the monitor reliably detects that threshold.
Does the carrying case protect the cylinder during transport?
Yes. The hard carrying case holds the calibration cylinder, regulator, and tubing in organized compartments for field transport. This keeps all components together and protects the cylinder valve during handling. Ensure the cylinder valve is closed and the regulator is removed before transporting.
Why is calibration gas non-returnable?
Calibration gas is a hazardous material with a fixed certification date and concentration lot number. Once shipped, cylinders cannot be re-inspected or restocked. Confirm the monitor model and sensor type before ordering. Call
800.829.9580 for pre-purchase verification.
Can PK Safety service or calibrate the OX-04 Series monitor?
Yes. PK Safety services RKI Instruments monitors in-house with factory-trained technicians, including the OX-04 Series. Services include calibration, O2 sensor replacement, and full inspection. Call
800.829.9580 to arrange service or request a return authorization.
