Product Description
4-Gas Calibration Gas for Multi-Gas Detector Calibration and Bump Testing (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed for verifying the accuracy of portable gas detection instruments used to monitor toxic gases, combustible gases, and oxygen levels in hazardous industrial environments.
The mixture includes Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, balanced with nitrogen. These concentrations are commonly used during routine detector calibration and bump testing to confirm proper sensor response.
Supplied in a 120-liter aluminum cylinder pressurized to 1050 PSI, this calibration gas provides extended capacity for facilities maintaining large fleets of portable gas detectors or performing frequent calibration procedures.
The C-10 valve outlet ensures compatibility with calibration regulators commonly used with portable gas detection instruments.
