Product Description
4-Gas Calibration Gas for Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-component calibration gas mixture is designed to verify the response and accuracy of portable multi-gas detectors used in hazardous work environments where toxic gases, combustible gases, and oxygen levels must be monitored simultaneously.
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 sensor performance across multiple channels during bump testing, calibration verification, and routine instrument maintenance.
Supplied in a 60L aluminum cylinder pressurized to 1000 PSI, this calibration gas provides a compact yet efficient option for field technicians responsible for maintaining gas detection equipment.
The C-10 valve configuration ensures compatibility with commonly used calibration regulators designed for portable gas monitoring instruments.
