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.

Evikon Ammonia detector-transmitter E2608-NH3-E is a member of the new PluraSens® family of multifunctional measurement instruments. The instrument is intended for leakage control in refrigeration facilities, warehouses, etc. It is not recommended to use the device in spaces with constantly high ammonia concentrations such as cattle, pig, and poultry livestock houses, since it shortens the sensor lifetime.  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 concentration control. Two alarm set-points are user settable. Two analog outputs and an RS485 digital interface with industry-standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
