Product Description
4-Gas Calibration Gas for Multi-Gas Detector Bump Testing and Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed for verifying the performance of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous industrial environments.
The mixture 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 validate detector response during bump testing and scheduled calibration procedures.
Packaged in a 44-liter aluminum cylinder pressurized to 750 PSI, this calibration gas cylinder offers a compact and reliable solution for routine instrument maintenance and field service work.
The C-10 valve outlet ensures compatibility with standard calibration regulators commonly used with portable multi-gas detection equipment.
