2.4 Intended use
_
_
G 1500
The product is designed for measuring the pH value in water and aqueous media by
means of suitable electrodes.
_
_
G 1501
The product is designed for measuring the pH value and Redox by means of suitable
electrodes in water an aqueous media. Temperature compensation takes place auto-
matically with a connected temperature sensor.
Application examples for this are, for example, drinking water, waste water, surface
water, swimming pools, fish breeding and process chemistry.
