Dpstar is an authorized distributor of Evikon. Evikon is an instrumentation company, specializing in the development, manufacturing, and marketing of sensor-based electronic measurement instruments for industrial and building automation applications. Our mission is to provide businesses and organizations with convenient and efficient technical solutions for the measurement of environmental parameters and control of processes – temperature, pressure, level, humidity, and moisture, toxic and explosive gases – to help save resources, increase production quality and ensure safety.

Ethylene oxide detector-transmitter E2608-EtO is a member of new PluraSens® family of multifunctional measurement instruments. The instrument utilises a fully calibrated and temperature-compensated electrochemical gas sensor with excellent repeatability, stability and long lifetime. Two relays with closing contact may be used for remote signaling or ventilation control. Two alarm set-points are user settable. Two analog outputs and an RS485 digital interface with industry-standard Modbus RTU protocol can connect the detector to safety or building automation systems.



  • Chemical and polymer industry
  • Medicine (hospital sterilization facilities)
  • Areas where leakage or generation of ethylene oxide is possible.
