rH, pH

The highly compact pH/rH(mV)-controller with USB logger type M3020 has been developed for simple process control and monitoring applications in electrometry. The back lighted graphic display is readable from distance and enables self explaining activation of the functions.

• programmable
• very compact dimensions
• 2 limit contacts
• USB data logger

The highly compact pH/rH(mV)-controller type M3020 has been developed for simple process control and monitoring applications in electrometry. The back lighted graphic display is readable from distance and enables self explaining activation of the functions.

• programmable
• very compact dimensions
• 2 valve contacts
• for highly nonlinear titration curves
• USB data logger

The very small measuring amplifier for pH and Redox type M3720 converts the electrode signal to a 4…20mA 2-wire signal. The M3720 works with a resolution of 12 bit, is pre-calibrated and connected between the electrode and the signal acquisition instrument (e. g. PLC).

• 0...14pH, -1000...+1000mV
• output 4...20mA, 2-wire-technics
• modbus
• temperature compensation
• hold function

The pH/mV-controller type M2120 has been developed especially for applications which, until now, could not be monitored and controlled automatically due to cost.

• 2 alarm contacts
• temperature compensation to 120ºC
