Product Description
4-Gas Calibration Gas for Portable Gas Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the response accuracy of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in industrial safety environments.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 300 PPM, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0%, balanced with nitrogen. These concentrations allow technicians to evaluate detector response across multiple sensing channels during bump testing and scheduled calibration procedures.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI, this calibration gas cylinder offers a lightweight and portable solution for technicians performing routine detector calibration in the field.
The C-10 valve connection ensures compatibility with standard calibration regulators used with most portable gas detection instruments.
