Toxic & Refrigerant Gas Sensor Range

SST Controls range of NDIR toxic and refrigerant sensors cover hydrocarbon and HFO HFC and HCFC gases with more gases being added as they become available.

SIL2 approvals provides Functional Safety compliance for system integration and versions of ambient and flow through (aspirated) housings are available.

Fully temperature compensated and with voltage outputs (optional Modbus) these sensors are easy to fit and integrate into a system.

Inserted into our NDIR EXD housings provides a stainless steel industrial enclosure with the added benefit of hazardous area approvals.
