Gasmaster GM Gas Leak Detector<\/span><\/h2>\n

Stationary Gas Leak Detector <\/strong>Gasmaster GM 4 \/ (ATEX-certified) \/<\/strong><\/h2>\n

For configuring up to 4 gas sensors \/ for O2, O3, CO, CO2, NH3, and H2S<\/strong><\/h2>\n
\n
\n
The Gasmaster GM-4 gas leak detector is a reliable, stationary gas alarm device. To connect the gas detector, the gas meter is optionally equipped with one to four 4\u201320 mA or mV signal inputs. Each signal input has two alarm relays, which the gas detector can use to control, for example, signal lights, an audible alarm, or fans. The device has two additional relays built in for alarms 1 and 2. The GasMaster gas alarm system also includes a third relay for error messages. A large display shows measured values in ppb, ppm, or %. Additionally, the gas detector can be equipped with an optional interface for computer configuration or for uploading event logs. <\/span><\/div>\n<\/div>\n<\/div>\n
