Digital Memosens sensors: with its good galvanic isolation the Memosens prevents interferences, allowing straightforward and safe measurements even with most difficult potentials. The sensors can be easily handled under adverse conditions - you can even connect them under water.

Most versatile hazardous and safe-area applications, such as in industry, in the lab, for environmental protection, food processing, as well as water or waste-water treatment.

Portable pH meter with data logger, USB port and lithium-ion batteries. Data can be easily transferred to a computer for analysis using the USB interface and the incl. Paraly SW 112 software.
  • Li-ion battery.
  • Data logger with 5000 values.
  • Micro USB port and Paraly SW 112 software.
  • Memosens sensors and analog pH sensors can be used on one device (e. g. flat-membrane sensors).
  • The mineral glass display is perfectly readable even after years.
  • LCD STN 7 segment display.

The data logger:
The meter provides a data logger. Prior to use, it must be configured and then activated. The following logging types can be selected:
  • Manual logging by pressing the softkey.
  • Time-controlled logging at a fixed interval.
  • Signal-controlled logging of measured value and temperature.
  • Combined time- and signal-controlled logging.

The data logger records up to 5000 entries, which can be assigned to different measuring points (TAGs) and annotations.
