Gas Sensors

The Gemlog Controls team has a high level of expertise and many years of collective experience in a variety of gas detection technologies including Electrochemical, Catalytic, Optical and Semiconductor to ensure that we offer the best technology solutions to each customer's requirement. As a completely independent system supplier, we work in the strictest confidence with our customers to give you the system solutions you want.

Our range of gas sensors and transmitters cater for monitoring combustibles, toxic and inert gases. In excess of 40 different gas types using electrochemical, semiconductor and infrared technologies.

The sensor design provides the foundation for gas detection systems that perform continuously with minimal maintenance. The sensors are rated for temperatures from -20°C to + 40°C and have excellent zero stability and high sensitivity. All sensors are close coupled to the transmitter for excellent noise immunity and the ability to transmit over long distances using two or three core shielded cable.Typical Oxygen Sensor Specification:
