Product Description
4-Gas Calibration Gas for Multi-Gas Detector Testing (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to confirm the accuracy and response of portable gas detection instruments used to monitor toxic gases, combustible gases, and oxygen levels in hazardous work environments.
The blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 20 PPM, Methane (CH₄) 1.5% (30% LEL), and Oxygen (O₂) 20.9%, balanced with nitrogen. These concentrations allow technicians to verify detector sensor performance across multiple sensing channels during routine bump testing and calibration procedures.
Supplied in a 44L aluminum cylinder pressurized to 750 PSI, this calibration gas provides a convenient and portable option for technicians responsible for maintaining portable gas detectors in the field or within facility safety programs.
The C-10 valve connection ensures compatibility with standard calibration regulators commonly used with portable gas monitoring equipment.
