Welcome

Gas Sensing Solutions (GSS) supplies world leading CO₂ gas sensors.

The patented technology utilises unique III-V solid state light emitting diodes and photodiodes, replacing high cost incandescent light sources and pyroelectric detectors used in standard NDIR sensors. GSS CO₂ gas sensors incorporate gold plated injection moulded collection optics using patented optical designs, maximising pathlength and sensor sensitivity. GSS CO₂ sensors are 100% tested and calibrated over a wide temperature range before release to customers.

GSS offer analogue and digital electronic interface options that provide a temperature compensated and linearised CO₂ measurement which can be customised to suit specific customer product requirements. GSS sensors are available over a wide sensing range from 200ppm to 100%, with sensor range customised to suit specific customer requirements. We have divided our applications capability into the following categories: HVAC/IAQ, Diving, Automotive, Educational, Industrial / Safety & Horticulture. Browse your area of interest and please contact us when you need more information.

Benefits of the solid state NDIR approach include:

• Low power (< 100mW)
• Fast response (T90 < 4sec)
• -25 to 55 C Linearised and Temperature Compensated Output
• Range 200ppm to 100%
• Scaleable for high volume low price
