Your gas monitor needs to be bump tested and calibrated regularly to make sure it is functioning properly. This 34 Liter standard bump test and calibration gas for BW Honeywell gas detection units contains specific gas concentrations.
- Methane (CH4) - 2.5 percent
- Oxygen (O2) - 18.0 percent
- Hydrogen sulfide (H2S) - 25 ppm
- Carbon monoxide (CO) - 100 ppm
Please Note: Because of HazMat restriction, calibration gas must be shipped UPS Ground. Also note BW 4-gas calibration mix has a shelf life of two years. Don't use expired gas to calibrate or bump test a monitor.
Please Note: Calibration gas is not returnable. Please check your selection carefully before ordering.
