key sensor features
Introducing our ozone O3 gas digital SNMP & Modbus TCP sensor designed for detecting and measuring the level of ozone in the ambient air. For up to 20ppm.

no pc required for the ServersCheck to operate once configured - measures ozone gas concentrations up to 20ppm
- resolution: 0.1ppm
lab calibrated against ozone reference gas
- 2 year life span

- sensors for 20+ other gas types

- compact plug & play sensor.
- designed for indoor use.
- steel enclosure for non-power sensors or non-IP sensors. custom color & logo options available.
- industrial grade.
- 0u rack, DIN rail, magnetic or wall mountable sensor.
- plugs into the base unit.
- powered by the base unit (PoE, 12v DC, optionally 24v or -48v)
- alerts via SNMP Traps, email or SMS.
- out of the box integration via Modbus TCP, SNMP.
- optional integration via MQTT for Industrial IoT applications1New feature.
- optional integration via RS-485 enabling direct integration with your own gateway & controllers.2New feature

1Requires FW 10 or higher
2Some sensors are not available in RS-485 native versions. In that case RS-485 is available using the optional Modbus RTU module.

Partial discharges (PD)
for medium voltage switchgears
The corona discharge is one of the main causes of medium voltage (MV) switchgear equipment failure, ageing and losses in a stable power system supply. It often goes undetected until the next manual inspection.

Next to inspections, companies today rely on electromagnetic and ultrasonic methods to detect PD. Those solutions suffer from interference and high costs.

Less known is that partial discharges resulting from the Corona effect, generate ozone gas. By digitally monitoring ozone gas levels in MV switchgear, PD events can be detected and alerts can be generated to maintenance staff for immediate inspection.

calibration & bump testing
Prior to shipping every gas sensor is manually tested in our lab against calibrated gas.

For bump testing we offer the optional SPARE-GAS-BUMP adapter which is mounted on to the sensor. It enables you to self test the sensor at intervals to ensure its operation within your own safety & operational requirements. Do note that each bump test impacts the sensor life span and accuracy. Incorrect bump testing may permanently damage the sensor.

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 threshold levels have been detected. For example you can start a fan as soon as a specific is detected.
