Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is used for calibration and bump testing of portable multi-gas detectors used in confined space monitoring, industrial hygiene programs, and hazardous atmosphere detection.
The certified blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen. These concentrations allow technicians to verify sensor response across multiple detection channels used in standard multi-gas monitoring instruments.
Supplied in a 60L aluminum calibration cylinder pressurized to 1000 PSI, this calibration gas provides an ideal balance between portability and capacity for safety technicians performing regular detector maintenance and verification.
The C-10 valve configuration ensures compatibility with common calibration regulators used with portable gas detection equipment.
