Product Description
4-Gas Calibration Gas for Portable Detector Calibration (H₂S / CO / CH₄ / O₂)
This four-gas calibration mixture is designed to verify the performance of portable gas detectors used to monitor toxic gases, combustible gases, and oxygen levels in hazardous environments.
The blend contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 20 PPM, Methane (CH₄) 1.5% (30% LEL), and Oxygen (O₂) 20.9%, balanced with nitrogen. These concentrations allow technicians to test detector sensor response across multiple channels during bump testing and scheduled calibration procedures.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI, this compact calibration gas solution is ideal for technicians performing portable detector calibration in the field or servicing multiple job sites.
The C-10 valve connection allows compatibility with standard calibration regulators commonly used with portable gas detection instruments.
