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 that monitor toxic gases, combustible gases, and oxygen concentrations in hazardous environments.
The blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.62% (32% LEL), and Oxygen (O₂) 19.0%, balanced with nitrogen. These concentrations allow technicians to confirm proper sensor response across multiple gas channels during calibration and bump testing procedures.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI, this compact calibration gas solution is ideal for technicians performing field calibration or routine instrument verification.
The C-10 valve connection allows the cylinder to be used with standard calibration regulators commonly used with portable gas monitoring instruments.
