Product Description
4-Gas Calibration Gas for Portable Gas Detector Verification (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the response accuracy of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in industrial safety environments.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen. These concentrations allow technicians to confirm proper detector sensor response during bump testing and scheduled calibration procedures.
Supplied in a 44L aluminum cylinder pressurized to 750 PSI, this calibration gas offers a convenient and portable option for field technicians maintaining gas detection equipment.
The C-10 valve connection ensures compatibility with commonly used calibration regulators designed for portable multi-gas detectors.
