Product Description
4-Gas Calibration Gas for Portable Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed for verifying the accuracy of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous work environments.
The mixture contains Hydrogen Sulfide (H₂S) 20 PPM, Carbon Monoxide (CO) 60 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, balanced with nitrogen. These concentrations are commonly used when performing routine bump tests and scheduled calibration procedures on portable multi-gas detection instruments.
Packaged in a 66-liter aluminum cylinder pressurized to 1150 PSI, this calibration gas cylinder provides reliable capacity for technicians servicing gas detection equipment across industrial facilities.
The C-10 valve outlet ensures compatibility with commonly used calibration regulators designed for portable gas detection instruments.
