Introducing our new calibration free flammable gas sensor for detecting multiple gases: hydrogen (H2), butane (C4H10), propane (C3H8), methane (CH4), ethane (C2H6), isobutane (CH3), octane (C8H18), pentane (C5H12), propylene (C3H6), toluene (C7H8), xylene (C8H10). Target gas is selected via base unit or through Modbus register (RS-485 model). Sensor is designed for use in non hazardous, commercial and zone 2 classed environments like data centers, battery rooms, mechanical rooms, cooling rooms, warehouses and more.

- measures flammable gases between 0 to 100% LEL

1</sup>Requires BASE-XXX-6
²Some sensors are not available in RS-485 native versions. In that case RS-485 is available using the optional Modbus RTU module.

A modular architecture enabling you to integrate it with your on-premises monitoring systems using IP based industrial protocols like Modbus TCP and SNMP. Optional add-on to connect sensor data to a Modbus RTU controller. With our optional and special firmware the base unit can connect to a MQTT provider of your choice.

With the output controls of the SensorHub, the system can on its own take corrective actions when too high flammable levels have been detected. For example you can start a fan as soon as flammable gas is detected and trigger a siren when a maximum limit has been exceeded.
