With the M•Cal™ Calibration Station, calibrating, bump testing and charging the M40 Multi-Gas Monitor has never been easier or more cost-effective. Available in single- or six-unit versions, the M•Cal will accommodate all M40 monitors with software version 4.0 or higher in a diffusion mode or with an SP40 sampling pump attached. The M•Cal features simple, two-button operation allowing the user to quickly and easily calibrate or function (bump) test the instrument, and the LED indicators display whether or not the instrument passed or failed the desired function.

A PC is not required to operate this stand-alone system, making the unit extremely portable and flexible. Available accessories include an optional battery powered kit that enables the system to be used in remote areas, and a serial data printer that automatically prints calibration and bump test reports. The reports can be used for confined space entry permits with information pertaining to instrument serial numbers, pass/fail indications, bump test readings and full span readings for each sensor installed in the M40 monitor.
