The 1series analogue gas sensor is compact low profile sensor utilizing the trusted City Technology. These sensors have an extended operating life of five years along with extended temperature and humidity ranges.

The 3 Series range is City Technology's original gas sensor range. A wide variety of sensors are available in this format and are can be supplied with 4 mA to 20 mA and mV transmitter boards. The 7 Series is the natural replacement for the range.

City Tech’s 4-Series gas sensors are the industry standard for portable gas detectors. The range includes sensors which detect oxygen and toxic gases, carbon dioxide and hydrocarbons and fully certified pellistors for combustible gas detection.

City Technology’s 5 Series range of premium gas sensors has been designed to ensure optimal performance within the harsh environments of flue gas analysers and combustion efficiency monitors.

City Technology's 7-Series range is suited to general gas detection applications including oxygen and toxic gases. Sensors are suitable for use in portable or fixed gas detectors and medical gas applications.

Standard range of 400 ppm to 2000 ppm, up to 10000 ppm extended range. Accuracy of ±40 ppm ±3% of reading and ±50 ppm ±5% of reading

MICROceL® and MICROpeL® are City Technology’s smallest, most compact sensors. The range includes carbon monoxide, hydrogen sulphide and fully certified combustible gas sensors.

City’s MediceL® (MOX) sensors include oxygen and a range of other gas sensors that are designed specifically for use in respiratory and anaesthesia applications
