Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This 4-gas calibration mixture is designed for routine bump testing and calibration of portable multi-gas detectors used in industrial safety, confined space monitoring, and hazardous atmosphere detection.
The certified 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%, balanced with nitrogen. These concentrations allow technicians to verify the performance of multiple sensor channels used in common portable gas monitors.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI, this calibration gas provides a compact and lightweight option for field technicians performing frequent detector checks and routine safety verification.
The C-10 valve configuration ensures compatibility with common calibration regulators used with portable gas detection instruments.
