Product Description
4-Gas Calibration Mixture for Portable Gas Detector Testing (H₂S / CO / CH₄ / O₂)
This four-component calibration gas blend is designed to confirm the performance of portable gas detectors that monitor toxic gases, combustible gases, and oxygen levels in hazardous environments.
The mixture 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 test detector response across multiple sensing channels during bump testing, calibration verification, and routine instrument maintenance.
Supplied in a 66L aluminum cylinder pressurized to 1150 PSI, this calibration gas offers a portable yet efficient option for field technicians responsible for maintaining multi-gas detection equipment.
The C-10 valve configuration provides compatibility with commonly used calibration regulators for portable gas monitoring instruments.
