7. Product description

The measuring device enables the pH measurement of aqueous solutions in the range of pH 0 to pH 14. The pH is a
measure of the acidic or alkaline feature of an aqueous solution.
The pH electrode wears in use and over time. Due to the exchangeable electrode, a simple exchange in case of wear
is possible.
In addition, an optional redox probe for the measuring function "mV" (redox potential) can be connected. The measur-
ing device can be easily adapted to your measuring needs.
The pH and redox potential measurement is used in agriculture, horticulture, fish farming, aquariums, in the laboratory,
quality control or in the private sector.
The sensor for automatic temperature compensation or the redox sensor (ORP) is available as an option.

8. Power supply

The meter can be used mobile with battery or rechargeable battery. For this purpose, a commercial 9V block battery
is used.
