JUMO BlackLine Lf-GT with cell constants K=1.0
A special graphite is used as electrode material for the "GT" version. Measuring ranges of up to 100 mS/cm and more can be achieved by special graphite treatment and in conjunction with suitable evaluation devices. A temperature probe can be optionally integrated. The version with 120 mm installation length and a 12 mm shaft diameter permits the combined use of this conductivity measuring cell with commercially available pH and Redox electrodes in corresponding installation fittings. The probe is also particularly suited for connection to hand-held and laboratory measuring devices. When used as an online probe, suitable flow fittings must be used (see JUMO data sheet 20.2810, 20.2820, 20.2822).
JUMO BlackLine Lf-EC with cell constants K=0.01, K=0.1 and K=1.0
The main features of the "EC" version include the highly compact design and a Pt100 integrated as standard. With their 40 mm (or 63 mm) installation length, the probes can also be screwed into small nominal diameter pipes. For this purpose, the conductivity measuring cells come with a G1/2A or 1/2"-14 NPT thread.
The version with K=1.0 covers a measuring range of 0.1 to approx. 5000 µS/cm (5mS/cm). Here, titanium pins serve as measuring electrodes. The version with K=0.1 is designed as a coaxial measuring cell and can be used up to approx. 1000 µS/cm. Measuring cells with K=0.01 cover measuring ranges from 0.05 to 20 µS/cm. For this reason, they are highly suitable for use in pure and ultra-pure water treatment. In these measuring cells stainless steel 1.4571 is used as electrode material.
