Designed for the measurement of pH, ORP, conductivity, flow rate, turbidity and oxygen in high-end water-treatment applications, Kontrol 102 has a number of functions designed to simplify operation of even the most complex processes, from reverse osmosis to cooling water treatment. The unit features a Modbus RTU/ASCII protocol that allows remote control using an RS485 port, facilitating use in larger multi-site complexes. This dual-parameter controller also displays QR codes which can be scanned for quick and easy access to manuals, while the “electrode quality” control function assists the operator in the management and replacement of measuring electrodes. Plus, the multi-colour backlit screen is easy to read even in poor light and includes a reverse display function which allows on-screen text to be inverted for high contrast.
