JUMO BlackLine CR-GT
with the cell constants K = 1.0
The GT version features 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.
The 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 for this probe. The version with K=0.1 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.
