Product Description
4-Gas Calibration Gas for Portable Gas Detector Verification (H₂S / CO / CH₄ / O₂)
This quad-gas calibration mixture is formulated for verifying the accuracy and response time of portable multi-gas detectors used in hazardous work environments. The blend provides a balanced combination of toxic gas, combustible gas, and oxygen calibration points required for routine instrument maintenance.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 18.0%, with nitrogen serving as the balance gas. These concentrations allow technicians to confirm proper sensor performance across multiple detection channels during scheduled calibration or bump testing procedures.
Delivered in a 116L aluminum cylinder pressurized to 1000 PSI, this calibration gas provides an efficient option for facilities that perform frequent detector maintenance while still maintaining manageable cylinder size for field use.
The C-10 valve connection ensures compatibility with standard gas calibration regulators used with most portable gas monitoring equipment.
