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), 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
  • O2 offset <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), 4 & 7 Series formats the sensor has a 15 month operating life in normal use. It also 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.

HPM Series Particle Sensor
The Honeywell HPM Series Particle Sensor is a laser-based sensor which uses the light scattering method to detect and count particles in the concentration range of 0 μg/m3 to 1,000 μg/m3 in a given environment. A laser light source illuminates a particle as it is pulled through the detection chamber and as particles pass through the beam, the light source becomes obscured and this is recorded on the detector. The light is then analysed and converted to an electrical signal to calculate concentrations in real time.
