Description

The measuring devices of product group 202710 are battery-operated hand-held units intended to define the following measured values:
- pH value, Redox potential and temperature, or
- conductive conductivity and temperature respectively
in laboratories, industrial plants, in waste water treatment, in fish-keeping or fish-farming, etc.
The devices feature a min. and max. value memory and a hold function.
To extend the longevity of the battery, the device can be automatically shut down within a time span of 1 minute to 2 hours. Continuous measuring is also possible. The devices are operated using a membrane keypad.
The 202710/20 version is a device measuring the pH value, the Redox potenzial as well as the temperature. It is equipped with a manual or automatic temperature compensation for the measured value. The available Pt 100 temperature probe is an optional feature.
A commercially available single-rod electrode is connected to a BNC socket.
The single-rod electrode can be adjusted by means of 2-state calibration.
The 202710/30 version is a device measuring conductive conductivity and temperature.
The pre-installed conductivity measuring cell is equipped with graphite electrodes and features a cell constant of 1.0 1/cm. The temperature probe for automatic temperature compensation is integrated in the measuring cell. The hand-held measuring device permanently displays the conductivity compensated to 25°C. The automatic measuring range selection ensures that the measured value is always displayed in the optimal measuring range. This function can also be disabled.
