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.

CO-NO2 detector-transmitter E2660R-CO-NO2 is  an easy-to-use instrument intended for simultaneous monitoring of carbon monoxide and nitrogen dioxide concentration. It is an excellent solution for underground parkings. The device may be also used in boiler houses and other confined spaces, where potentially toxic concentration of carbon monoxide and nitrogen dioxide can accumulate. The instrument utilises novel fully calibrated and temperature compensated electrochemical gas sensors with excellent repeatability, stability and long lifetime. Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the transmitter to safety or building automation systems.
