Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Verification (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is formulated to verify the performance of portable gas detection instruments that monitor toxic gases, combustible gases, and oxygen concentrations in hazardous work environments.
The blend contains 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 allow safety technicians to confirm proper sensor response during routine bump testing and calibration procedures.
Packaged in a 34-liter disposable aluminum cylinder pressurized to 500 PSI, this calibration gas provides a convenient solution for portable detector maintenance where compact cylinders and easy transport are preferred.
The C-10 valve connection allows the cylinder to be used with standard calibration regulators designed for portable multi-gas detectors.
