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 H2.

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)
- lab calibrated against 50% reference gas either for H2 or CH4
- also sensitive to methane, propane and iso-butane
- proven sensor component made in Japan

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

- compact plug & play sensor.
- designed for indoor use.
- steel enclosure for non-power sensors. custom color options available.
- industrial grade.
- 0u rack, DIN rail, magnetic or wall mountable sensor.
- plugs into the base unit.
- powered by the base unit.
- alerts via SNMP Traps, email or SMS.
- wired or optionally wireless.
- integrates via Modbus TCP, SNMP.

- optional MQTT integration - requires a different firmware of the BASE-WIRED.
- Modbus RTU RS-485 hardware versions available for specific sensors enabling direct integration with your own gateway & controllers.
- for other sensors, integrates over RS-485 is available using the optional Modbus RTU module.

- Gas and Thermal Imaging sensors require the optional BASE-FW-SSLS firmware addon to operate.

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.

lab & bump testing
Prior to shipping every H2 sensor is manually tested in our lab against a 50% LEL hydrogen gas.

For bump testing we offer the optional SPARE-GAS-BUMP-H2 adapter which is mounted on to the sensor. It enables you to self test the sensor at frequent intervals to ensure its operation within your own safety & operational requirements.
