BW Honeywell 4-Gas Calibration Mix BW01-CG-Q34-4
Bump test and calibrate your 4-gas monitor regularly with the BW calibration gas mixture. This 34 Liter calibration gas cylinder has a shelf life of two years. Never calibrate or bump test a gas detector with expired gas.
- CH4 (2.5 percent)
- O2 (18.0 percent)

How many monitors will this product calibrate?1 answer
While there is no exact number of calibrations offered by the CG-Q34-4 quad cal gas, I can offer some guidelines. The recommended constant flow regulator for diffusion instruments puts out 0.5 liters per minute. The BW GasAlert Max gas detector has a 2 minute calibration cycle. One half liter per minute x 2 minutes = 1 liter of cal gas per calibration. Given that the cylinder contains 34 liters of gas, we should get approximately 34 calibrations.
There are certainly variables here. How precisely the regulator is cycled on and off, how many bump tests you might do, etc. On pumped instruments, such as the GasAlert Max XT II, a demand flow regulator may be used in place of the constant flow type. This can conserve gas, as gas only flows when the instrument is pumping.
