PH / ORP / TDS / Conductivity are the primary controlling parameters for any process used in a wide variety of industries ranging from water, chemical, pharmaceutical, food processing, etc. Our online controllers are used to monitor these process parameters continuously and help to take corrective action with their relay & current outputs. These reliable, accurate, and robust meters are designed with a compact housing that fits in standard industry panels. Also, these meters can be easily calibrated and can display multiple parameters at the same time.
