Our Top Sensors

TYPICAL SENSORS SUPPLIED

• Industrial safety sensors
• Medical sensors
• Ventilation / underground sensors
• Fruit Ripening sensors
• Residential Safety sensors
• Refrigeration sensors
• Infrared sensors for Carbon Dioxide and Hydrocarbons
• PID for the detection of volatile organic compounds
• Pellistors for combustible gas detection
• 1 SERIES: The 1series analogue gas sensor is compact low profile sensor. These sensors have an extended operating life of 5 years along with extended temperature and humidity ranges.
• 3 SERIES: In the 3 Series range A wide variety of sensors are available in this format and are can be supplied with 4-20mA and mV transmitter boards. The 7 Series is the natural replacement for the range.
• 4 SERIES: The 4-Series gas sensors are the industry standard for portable gas detectors. The range includes sensors which detect oxygen and toxic gases, an infrared version for carbon dioxide and hydrocarbons and fully certified pellistors for combustible gas detection.
• SENSORIC: Sensoric toxic gas sensors. Over the last 20 years, the range has gained worldwide recognition for excellent performance, particularly for detecting exotic gases. Sensors are available in a small 'mini' housing or can be supplied with adaptors to fit the 4- and 7-Series format. Sensoric sensors are also available with 4-20mA transmitter boards.
• 5 SERIES: This range of premium gas sensors has been designed to ensure optimal performance within the harsh environments of flue gas analysers and combustion efficiency monitors. Sensors are available for oxygen, carbon monoxide, nitric oxide, nitrogen dioxide and sulphur dioxide, along with a hydrogen-compensated carbon monoxide sensor.
• MICRO: MICROceL® and MICROpeL® are one of the smallest, most compact sensors. The range includes, carbon monoxide, hydrogen sulphide and fully certified combustible gas sensors.
• 7 SERIES: The 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.
• MEDICAL: The (MOX) sensors include oxygen and a range of other gas sensors that are designed specifically for use in respiratory and anaesthesia applications.
• ECOSURE: The ECOSURE range is designed for high quality CO detection in residential and commercial environments.
