The GMI Protege ZM is a disposable, portable single gas detector that operates by a single button. Models are available for Carbon Monoxide, Hydrogen Sulphide and Oxygen. It comes ready for use with a lithium-based battery, filter and sensor.
Maintenance-free, once activated, no charging or calibration is needed. If used in default mode, no programming is required. The user can configure alarm settings via software and the IR Connect or test station accessory.
Gas indication is by a direct-reading backlit LCD, with multiple bright LEDs, a loud audible alarm (95db) and vibratory alarm. Remaining operational life or real-time gas readings or both can be displayed.
Featuring a 24-month life. CO and H2S versions have a hibernate feature which extends battery life by up to a year.
The monitor includes a downloadable data log for twenty-five events, recording exposures, calibrations, and gas values. These can be downloaded to a PC using the software included or by an optional IR connection module, which can also be used for calibration, hibernation and programming of monitors.
