Product Description
Five-Gas Calibration Mixture for PID & Confined-Space Detector Programs
This five-gas calibration mixture combines Hydrogen Sulfide (H₂S), Carbon Monoxide (CO), Methane (CH₄), Isobutylene (C₄H₈), and Oxygen (O₂) in a 34L aluminum cylinder with nitrogen balance, formulated for verifying advanced multi-sensor gas detectors used in confined spaces, refineries, chemical plants, and municipal utility systems.
The inclusion of isobutylene makes this mixture ideal for validating PID sensor response while simultaneously checking toxic, LEL, and oxygen channels in a single calibration cycle — reducing downtime during safety inspections and shutdown work.
