JUMO BlackLine CR-GT
with the cell constants K = 1.0
The GT version features a special graphite as the electrode material. The graphite has been
especially treated to achieve - in conjunction with suitable evaluation devices - measuring
ranges up to 100 mS/cm and above.
A temperature probe can optionally be integrated. The conductivity sensor with 120 mm fitting
length and a shaft diameter of 12 mm can be used in combination with standard pH or redox
electrodes in suitable built-in fittings. The sensor is also ideally suited for linking with handheld
or laboratory measuring equipment. When used as an online sensor, suitable flow-through
fittings must be employed (see JUMO data sheets 202810, 202820, 202822).
JUMO BlackLine CR-EC
with the cell constants K = 0.01, K = 0.1 and K = 1.0
The principal features of the EC version are its very compact construction and the Pt100 that is
integrated as standard. With a fitting length of just 40 mm (or 63 mm), the sensors can also be
screwed into pipelines with a small nominal diameter. To this end, the conductivity sensors
either have a G 1/2A or 1/2"-14 thread.
The version with K = 1.0 achieves a measuring range of 0.1 to about 5000 µS/cm (5mS/cm).
Titanium pins function as the measuring electrodes here. The version with K=1.0 has been
implemented as a coaxial cell and can be used to about 1000 µS/cm. Sensors with K = 0.01
cover ranges from 0.05 to 20 µS/cm. They are therefore extremely suitable for pure and high-
purity water applications. The electrode material for these sensors is stainless steel 1.4571.
JUMO BlackLine CR-GS glass conductivity sensors K = 1.0
Glass conductivity sensors are used to conductively determine the electrolytic conductivity of
aqueous solutions. The cell constant of the sensor is K = 1.0
1
/
cm
. These sensor can be supplied
with an integrated Pt100 masuring insert, as an option.
Versions with a Pg13.5 threaded cap can be incorporated in suitable fittings (sse data sheets
202810, 202820, 20,2822 and 202825).
Operating principle
The sensors in the 202922 series are 2-electrode conductivity sensors. A transmitter applies an
AC voltage to the sensors. The current flowing through the liquid and the electrodes is
determined by the conductivity of the liquid.
