Long-Life lead-free oxygen sensors

  • Our lead-free sensors are RoHS compliant, future-proofing our customers instruments against the upcoming ban on the use of lead in electrochemical sensors.   

  • DDS lead-free sensors have a working life of 5+ years - negating the need for 2 or 3-year device maintenance. 

  • Our lead-free sensors have best-in-class response times and are resilient to challenging environments.

  • We are glad to provide comprehensive technical support to customers who are switching from lead to lead-free sensors. 

Dual Toxic - Carbon Monoxide & Hydrogen Sulphide

  • Our Dual toxic sensors are available with a choice of two operational ranges 0-1000 ppm CO / 0-200 ppm H2S in the industry standard 4-series format and 0-1000 ppm / 0-100 ppm H2S in the compact DceL format.

  • Key benefits of DDS dual toxic sensors are high stabilty, fast response/recovery and extremely low H2S cross-sensitivity on the CO electrode.

  • With the ability to meet high-volume requirements whilst delivering consistent high-quality, DDS are the first choice provider of Dual Toxic sensors to many of the worlds leading instrument and device OEMs.

First choice for North American car parks

Gas detection in the car park sector ensures safety of people and facilities by monitoring hazardous gases such as those associated with exhaust fumes and flammable vapours. Early detection of gas leaks or elevated gas levels protects occupants and workers, prevents health risks, and reduces the likelihood of fire or explosion incidents in enclosed parking facilities.

Gases typically monitored within the Car Park Sector include;

  • Carbon Monoxide (CO)
  • Nitrogen Dioxide (NO2)
  • Methane (CH4)
  • Oxygen (O2)
  • Volatile Organic Compounds (VOCs)

Many of the sensors we make for this sector are certified to UL2075. 

Are you ready for the Hydrogen Economy?

  • Our range of H2 sensors includes those which detect from 0-1000 ppm, 0-5000ppm and 0-50000ppm, satisfying a broad range of applications.

  • We manufacture H2 sensors in the industry standard 4-series format as well as the 7 series, commonly used in fixed applications.

  • Key benefits of DDS H2 sensors include fast response, low CO cross-sensitivity, high stability and extended range making them effective in applications ranging from process control to early detection of battery fires. 

  • With the ability to meet high-volume requirements whilst delivering consistent high-quality, DDS are the first choice provider of H2 sensors for a many of the worlds leading OEMs.
