control the conductivity of the cooling water is mandatory and is done through measuring instruments or conductivímetros. These instruments, we can even automate the process of purging and conduct operations depending on the extent of the conductivity continuously. Currently, COYD, markets a wide range of equipment for this application, ranging from computers to measure individual panels complete and ready to connect to the installation.

It is a technologically advanced tool that allows making careful adjustments to the conductivity in industrial applications. The LCD display is 15 mm high digits for that can be read in areas with direct sunlight or from a distance of 5 meters. The box is made of plastic, particularly robust, with an index of protection IP65. The instrument is easy to use. The configuration base is achieved through 6 microswitches determining the reference temperature 20 or 25 ° C, the type of action of the relays, action The alarm NA or NC and the protection of programming and calibration functions. The measuring probe is calibrated in a very Simple. The measurement is compensated in temperature manual or automatic with three-PT100 threads. The temperature is viewable with the push ° C.
