All gas-powered devices have the potential to release dangerous gas. As soon as the GXHS gas detector detects such gases, it automatically interrupts the power supply and, optionally, the gas supply through the gas line. Depending on the type of sensor connected, the device detects town gas and natural gas (methane/butane), coolants and refrigerants, or carbon dioxide used in the catering industry or from the air we breathe. The GX-HS device features an output for an external buzzer. The input also offers two setting options (via wire jumper). The triggered alarm can be saved and acknowledged by pressing a button. The alarm can also be automatically cleared when the gas concentration falls below a certain threshold.
Gas sensor connection: Only one gas sensor can be connected to the GX-HS gas detector at a time. https://youtu.be/oTxMdmamv_M
Areas of application
- Detection of town, natural and liquefied gases (GX-SE)
- Indoor air (GX-CO2-25 and GX-DS)
- Gastronomy CO2 monitoring (GX-CO2-30)
- Air conditioning systems, fluorinated refrigerants (GX-CFC)
- Only one sensor can be connected to a GX-HS 24V
