Your G.A.S.-pro/G.A.S.-pro III already reliably warns you of escaping gases such as propane, butane or anesthetic gas. But carbon monoxide can also be life-threatening. The CO sensor detects the odorless gas and warns you in good time. Carbon monoxide can escape, for example, if the gas heating system is faulty. As it is imperceptible to the human sense of smell, no vehicle should be without a CO sensor. The carbon monoxide sensor is equipped with a 4 m long (extendable to 7 m) connection cable and is mounted just below the vehicle ceiling. It also detects the carbon monoxide produced by a fire.
