Carbon Monoxide Calibration Gas 100 ppm

On a standard 4-gas monitor, CO (carbon monoxide) is one of four channels, alongside oxygen (O2), combustible gas (LEL), and hydrogen sulfide (H2S). The CO channel is typically calibrated to 100 ppm or similar low-ppm concentrations per OSHA 29 CFR 1910.146 confined space entry requirements. A certified 100 ppm CO calibration gas is used for bump testing and full calibration of these instruments.

CO calibration gas at 100 ppm is most commonly balanced in nitrogen or zero air, depending on the application. Nitrogen balance is standard for most detector and analyzer calibration, while zero air balance is preferred for combustion analyzer calibration, ambient air quality monitoring, and applications where the oxygen content of the balance gas matters for sensor response.

Yes. SpecGas produces EPA Protocol-grade CO calibration standards suitable for CEMS calibration under EPA Method 10, Performance Specification 4/4A/4B, and 40 CFR Part 75. These are NIST-traceable and can be used for Cylinder Gas Audits (CGA) and Performance Audits (PA) at power plants, boilers, incinerators, cement kilns, and refineries.

Yes. The 100 ppm CO calibration gas is suitable for bump testing and full calibration of portable single-gas and multi-gas detectors from major manufacturers including MSA Altair, Dräger X-am, Industrial Scientific Ventis/MX6, Honeywell BW Clip/MicroClip, RAE MultiRAE, RKI GX/EAGLE, Crowcon Gas-Pro, GfG G460, and others.

SpecGas offers CO calibration gas in both non-refillable (disposable) and refillable cylinder options. Disposable cylinders are available in aluminum and steel. Refillable aluminum and steel cylinders are also offered. Sizes range from 17-liter, 58-liter, to 103-liter capacity, covering field portable use through fixed station and laboratory applications.

SpecGas's proprietary internal cylinder treatment process is specifically engineered to extend the stability of reactive gas mixtures like carbon monoxide at low ppm concentrations. This process, backed by the SpecGas Stability Guarantee, helps ensure the mixture maintains accuracy throughout its intended shelf life. Exact shelf life depends on concentration, cylinder type, and storage conditions.
