Product Description
4-Gas Calibration Gas for Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is formulated to verify the response accuracy of portable gas detection instruments that monitor toxic gases, combustible gases, and oxygen levels in hazardous work environments.
The mixture includes 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 are commonly used during detector bump testing and scheduled calibration procedures to confirm proper sensor response across multiple channels.
Packaged in a 60-liter aluminum cylinder pressurized to 1000 PSI, this calibration gas provides a practical balance between portability and capacity for technicians maintaining gas detection instruments in the field.
The C-10 valve configuration ensures compatibility with industry-standard calibration regulators used with most portable multi-gas detectors.
