4OxLL and 5OxLL Oxygen Sensors

These long-life oxygen sensors are designed to work in an analyser for seven years, the entire life of the instrument. Available in 4 and 5 series formats, they offer an enhanced response time in extreme conditions. Based on “electrochemical pump” technology, the design avoids using a consumable anode (lead) so removing the life-limiting component of many sensors. This technology significantly reduces the cost of ownership and the occurrence of field failure, helping manufacturers reduce their servicing costs.

  • Available in 4 & 5 Series formats
  • Seven year life
  • Fast response & recovery times: T90 <15sec
  • O2offset <0.3%
  • Highly stable: <5% signal loss over lifetime.

Hydrogen Sulphide Sensors

Sensoric cells are designed for operation in a wide range of environments and harsh conditions. Based on 3-electrode electrochemical technology, the new 3E 2000 S is a very selective, high capacity sensor ideal for use in Landfill and Biogas applications.

Available in Mini, Classic, Smart (8 pin pocket) and 4 & 7 Series formats the sensor has a 15 month operating life in normal use. It has a fast response time: T90 < 60 sec, baseline offset: < ±250 nA and Lower detection limit: < 20 ppm.

A5F+ Carbon Monoxide Sensors

The new A5F+ provides extended range CO sensing (for use up to 20,000ppm) above the capacity of the established A5F sensor. This eliminates the need for a second sensor in instruments certified for ‘high range’ applications. The sensor uses a H2 compensated 4 electrode design and a high capacity SOx / NOx filter, providing over five years’ life in typical usage cycles. This sensor fully complies with EN50379-2 & 3.
