Product Description
4 Gas H2S CO CH4 O2 Calibration Gas – 66L Cylinder
This four-gas calibration mixture is designed for routine detector verification under normal atmospheric oxygen conditions. It allows technicians to confirm toxic and combustible sensor response while maintaining an oxygen level representative of typical ambient air.
Ideal for daily bump testing where oxygen alarm activation is not required.
