4-wire conductivity electrodes

Conductivity electrode

 

Conductive 2-wire or 4-wire electrode measuring cells for measuring electrolytic conductivity of a solution (the salinity).

4-wire conductivity electrodes


The 4-wire conductivity electrode consists of four electrodes (2 voltage electrodes and 2 current electrodes) which are made of special carbon with an integrated temperature sensor. The current electrodes provide the power necessary for the measurement. The voltage electrodes are used to determine the voltage drop in the measuring solution and to calculate the conductivity.

 

Advantages

– interfering polarization resistances do not influence the measurement
– minimal dependence of the measurement results on the electrode's degree of contamination
– no influence of the cable lengths for great conductivities

 

Usage: chemicals, laboratory, food industry, water management, environmental analysis

Bambach-BLUMATplug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
