key sensor features
no pc required for the ServersCheck to operate once configured - ASHRAE A3 class refrigerant gas sensor
- detects R-290 gas type
- measures refrigerant gas concentrations up to 10,000ppm
- resolution: 1 ppm
- lab tested against calibrated reference gas
- 5 years life span

- additional sensors available for 20+ other gas types

- 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.

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.
