What we do · pH

pH Meters & Process pH Control

We develop equipment that measures and regulates pH accurately, from benchtop pH meters to controllers integrated into processes.

Equipment we design and manufacture

  • Benchtop pH meters

  • Inline pH controllers

  • Probes and electrodes

  • Acid/base dosing systems

Every machine we build runs on a custom PLC

Each machine is controlled by a PLC (programmable logic controller) programmed specifically for your process: recipes, alarms, data logging, HMI touchscreen and connection to your systems. We develop it in-house, together with the machine.
