Cal Gas: 4-Mix Calibration Gas (CO 50ppm/CO2 5000ppm/CH4 2.5%/O2 20.9%, Balance N2) - 34L

Multi-gas mixture for monitor calibration.

Ensure maximum accuracy with your RAE monitors through effective and efficient calibration with our calibration gases. Stand-alone gas cylinders range in size from 11 liters to 103 liters, and convenient multi-gas mixtures enable calibration of multiple gases at once, including common mixtures such as carbon monoxide, hydrogen sulfide, and combustibles for LEL sensor calibration.
