The measuring instruments are equipped with a permanently installed
rechargeable battery for mobile use.
The instruments come in 5 basic versions, which differ in their design with
regard to different measuring channels and respective functions.
912 Conductometer
With a measuring channel for measuring conductivity, TDS and salinity.
913 pH Meter With an analog and a digital measuring channel each for measuring pH,
potential and temperature.
913 pH/DO Meter With an analog and a digital measuring channel each for measuring pH,
potential, temperature and oxygen.
914 pH/Conducto-
meter
With an analog measuring channel for measuring pH, potential and tem-
perature and a measuring channel for measuring conductivity, TDS, salinity
and temperature.
914 pH/DO/
Conductometer
With a digital measuring channel for measuring pH, potential, tempera-
ture and oxygen and a measuring channel for measuring conductivity,
TDS, salinity and temperature.
For stationary use in the laboratory, the instrument can be connected to
the energy supply with a dedicated power supply unit.
