Key Features

Concentration matched to the monitorThis is the four-gas mixture matching the PM400 published calibration gas defaults of CO 100 ppm, H2S 25 ppm, O2 18 % Vol and LEL 50 % LEL.

Bump test before each day of useMacurco specifies a bump test before each day's use, applying a known concentration to confirm that the sensor responds and the alarms activate.

Certified concentration requiredMacurco warns that using a gas at a concentration other than the one specified, or using expired gas, produces inaccurate readings that can mask a real overexposure.

Frequently Asked Questions

Which monitor does the 37-0551-3344-2 cylinder calibrate?

The AimSafety PM400 series. Each AimSafety monitor takes a gas and concentration matched to its own alarm set points.

How often should a bump test be performed?

Macurco specifies a bump test before each day's use. It is the only way to confirm that the sensor and all alarm functions are working correctly.

Does this cylinder ship as hazmat?

Yes. Macurco flags this calibration gas as requiring hazmat shipping, so shipping restrictions apply.

Can expired calibration gas be used?

No. Macurco warns that testing with expired gas or with a concentration other than the specified one produces inaccurate readings, which means higher levels of the monitored gas may be present than the display shows.
