TetraCon DU/T flow-through conductivity electrode (WTW, Germany)Product Introduction:
1、The electrode is carefully designed, with high accuracy and linearity
2、Electrode contamination does not affect testing accuracy,Automatic compensation for changes in electrode surface contact resistance
3、The testing scope is very wide
4、Wire impedance does not affect test accuracy
5、Graphite electrodes have excellent quality, wear resistance, and very stable electrode constants
6、The sample flows freely and is representative
7、Built in temperature probe
8、Not affected by polarization
9、Minimum immersion depth
10、The electrode material is epoxy resin, which is not fragile
In addition, we also have electrodes for special applications such as testing ultrapure water, boiler water, deionized water, etc. to choose from
