Product details


  • All important data at a glance, thanks to the high-resolution colour display (4.3″) with large digits and clear symbols
  • Simultaneous measurement and display of pH value and conductivity is possible
  • Simple and intuitive to use; menus with complete sentences in 12 languages
  • Electrode arm is easy to operate with one hand; electrode can be positioned securely by moving it up and down
  • Calibration with predefined and user-specific buffers and buffer groups is possible; calibration memory with optional sensor lock setting available; quality of the most recent sensor calibration shown directly via pH sensor symbol
  • Comprehensive safety functions both for routine measurements and measurements under strict GLP specifications
  • With two operating modes: in Routine mode, it is not possible to delete data or change settings; in Expert mode (secured with PIN code), all functions can be used by an authorised user
  • Internal measured value memory: saving by pressing key or timed (intermittent) saving (interval can be set between 1 s and 40 min)
  • USB ports for exporting data via USB stick (datasets are exported as a text (.txt) file) or for connecting a USB keyboard
  • Intelligent Sensor Management (ISM®) for automatic recognition of ISM® sensors and reading in calibration data
  • Sustainable with highest Energy Star rating for the power supply (low energy loss, low heat generation) and environmentally friendly packaging

General information

The redox potential can be measured with a pH meter, which can display mV values.A redox probe is needed for this.
