The  PH3030 (model 7685) has been developed with the experience of 50 years in the industrial electrochemical industry. The controllers were newly developed where quality, reliability, simplicity of use and cost were a requirement.

The microprocessor’s capabilities are supported by user-friendly software. This software has been specially developed to keep the use of the controller, programming of functions, routine checking and calibration simple, even for untrained persons.

Applications:

• pH and ORP measurement
