Product description

The new G.A.S.-pro III is a reliable gas alarm system with extended functions that is permanently installed in your vehicle. It detects all gases currently used in narcotic gas attacks as well as propane and butane, or deadly carbon monoxide in the second version, and warns you long before they become dangerous.

The new generation

The G.A.S.-pro III is the latest G.A.S.-pro generation. It has been on the market since 2020 and, together with the current G.A.S.-pro, rounds off our gas sensor range in the high-end segment. It has all the functions of the tried and tested G.A.S.-pro, but has also been significantly improved in many ways. The internal siren is increased to a powerful 94 dB. An integrated humidity sensor optimises the already precise measurement in case of high humidity in the vehicle or exhaled air in the direct vicinity of the sensor. In addition, an alcohol filter (liquid gas / KO gas sensor) eliminates false alarms caused by alcohol in the air. The current consumption of the new G.A.S.-pro III with integrated LPG/KO gas sensor is reduced to a minimum of 26 mA, with integrated CO gas sensor to just nine milliamperes.

Available in two versions

The G.A.S.-pro III is even available in 2 basic set-ups: the familiar one with an integrated LPG or narcotic gas sensor and one with an integrated CO gas sensor. Each of the two variants can be combined with an additional gas or CO sensor.

State-of-the-art safety

Thanks to the built-in wireless unit, the new G.A.S.-pro III only needs to be connected via the power cable to the on-board electrical system. After that, you can connect your new G.A.S.-pro III wirelessly to the central control unit via easy add. The easy add function allows you to teach a new component, such as the G.A.S-pro III, to the alarm system in just a few steps: start teach-in mode, switch on new accessories, end teach-in mode. That's it.
