Product Description
116L 4-Gas Calibration Gas – 300 PPM CO High-Alarm Validation
This 116L reactive 4-gas calibration cylinder supports structured validation of 300 PPM carbon monoxide high-alarm setpoints while confirming severe oxygen-deficiency response at 15.0% O₂.
Designed for operational programs requiring steady calibration cycles across multiple instruments.
Gas Mixture Details
-
Hydrogen Sulfide (H₂S): 10 PPM
-
Carbon Monoxide (CO): 300 PPM
