Product Description


The Protege ZM serves as the perfect cheap and cheerful single gas monitor that provides protection against a single gas. 

3 Key Features and Benefits

1. One Button Activation - Two Years of Service, Hassle Free
With one-button activation, adjustable alarm settings and an easy-to-read display the Protégé ZM is simple to use. Just turn it on for the first time, and the single gas detector does the rest.

Using the default settings from the factory there is no need to set up or program the monitor.

Once activated, the Protégé ZM monitor is hassle free for engineers. It does not require charging or calibration so these monitors can be deployed in the field 24 hours a day, every day for two years. 

2. Hibernation Mode - Extend Life by One Year

The H2S model includes a hibernate feature which allows you to extend your battery life up to one additional year.

The gas monitor is small, lightweight (76.5g), ergonomically designed and meets IP67 requirements for ingress protection.

The unique Protégé ZM profile fits your hand nicely, making the monitor comfortable to hold. It’s so lightweight and small you will forget you’re wearing it while it protects you
