Note: This item ships via UPS Ground due to HazMat restrictions and isn't available for expedited shipping.

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.

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.

Note: calibration gas is not returnable. Please check your selection carefully before ordering.

For the Following Monitors:
Please Note:
The Micro 5 PID also requires the Isobutylene Calibration Gas.

      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.

      The "use by date" is located on the label on the left hand side, under the lot number.
