key sensor features
Introducing our second generation digital SNMP & Modbus TCP sensor designed for monitoring 24x7 hydrogen H2 levels and detect leaks from lead acid and li-ion battery banks. For up to 100% LEL (lower explosive limit) or 40,000ppm

no pc required for the ServersCheck to operate once configured - measures hydrogen in the air between 0 to 100% LEL
- resolution: 100ppm
- with a ± 5% accuracy.
- precision of 1%.
- maximum detection of 40,000 H2 ppm (=100% LEL)
- proven sensor component made in Japan

- sensors for 21 other gas types like CO, CH4, HF, NH3

- compact plug & play sensor.
- designed for indoor use.
- steel enclosure.
- industrial grade.
- 0u rack, DIN rail or wall mountable sensor.
- plugs into the base unit.
- powered by the base unit.
- alerts via SNMP Traps, email or SMS.
- integrates via Modbus TCP, SNMP, JSON with other systems.
- integrates over RS-485 using Modbus RTU with ICS. Requires optional add-on.

modular architecture
hydrogen gas sensor architecture
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 hydrogen levels have been detected. For example you can start a fan as soon as hydrogen is detected and trigger a siren when a maximum limit has been exceeded.
