The MTG-3000HR detector is designed to monitor rooms for the presence of natural gas (LNG), methane, propane, butane or a mixture of propane-butane (LPG) in living spaces. We offer together with an adapter.

Compared to the MTG-3000H model, this model is also equipped with an output relay, which can be used to automatically close the gas supply, activate the security system, for external danger signaling, etc.

As one of the few flammable and explosive gas detectors in its category, it has certificates confirming compliance with the requirements of both Czech and European technical standards ČSN EN50194-1: 2009 and ČSN EN50194-2: 2006 issued by the independent accredited laboratory TÜV SUD Product Service GmbH in Germany.
Thanks to this confirmation of conformity, the detector can be installed not only in residential buildings, but also in caravans, motorhomes, caravans, boats and yachts.

The MTG-3000HR detector is designed to continuously detect the presence of flammable gases in the monitored area. Detection is provided by a catalytic combustion sensor, with high sensitivity, which does not require additional calibration.

If a gas leak is detected, an optical and acoustic warning signal is activated and an output relay is switched on, which implements the next step following the connected peripheral. The alarm will end after the gas concentration drops below the threshold value that activates the alarm. The device has an automatic diagnostics system that monitors the sensor and internal circuits. If the detector diagnostics detects any irregularities, the buzzer will sound and the yellow ERROR LED will flash.

The detector is powered by a safe voltage of 12V DC via a 230V / 50Hz mains supply, which is included in the package.

Areas of use: Living spaces with kitchens equipped with gas stoves, domestic boiler rooms with equipment burning natural gas, propane-butane or rooms in which gas equipment is located, such as: gas cylinders, tanks, gas pipes, garages for gas-powered cars , school chemistry and physics workshops and laboratories.

Where to install the detector?

We install flammable and explosive gas detectors in rooms with a potential gas leak (gas boiler rooms, kitchens, rooms with wavka, karma, direct heaters, heaters, etc.). The basic criterion for the correct placement of the detector is gas identification, i.e. whether we will detect light gas (rises up to the ceiling) or heavy gas (falls to the floor). We will choose the installation location according to this criterion. We always install the gas detector on the wall, depending on the type of gas detected, either under the ceiling (approx. 15-30 cm) or above the floor (approx. 15-30 cm), at a distance of at least 1.2 m from the fuel-burning device to minimize false alarms, which can occur during a short gas leak, for example when lighting a gas boiler or stove and at a distance of approx. 60 cm from the corners, i.e. the place where two walls meet.

Properties of gases and their weight relative to air

Propane Butane (LPG): Heavier than air, sinks to the floor.
Natural gas (LNG, CNG): Lighter than air, rises up to the ceiling.
Petroleum: Heavier than air, sinks to the floor.
Ethylene: Lighter than air, rises up to the ceiling.
