Conductivity Cells

Types of Conductivity Cell

2 electrode conductivity cell2 Electrode Cell
The two electrode cell is the most commonly used conductivity cell Glass cells have electrodes made of platinum. Epoxy cells have easy to clean graphite plates. The conductivity cells on this page do not have errors caused by fringe field effects because the entire measuring field is contained within the electrode body. This kind of probe can be used with almost any conductivity meter.
4 electrode conductivity cell4 Electrode Cells
The electrode design reduces the problem of polarization error and fouling of the electrode. (polarization comes about because electro-chemical reaction with the probe surface ). In the four electrode design alternating current is applied only to the outer pair of rings. The voltage is measured on the inner rings without polarization effects because no current flows in the measuring circuit. This type of probe is superior in function in almost any solution and covers the whole conductivity range with one probe,

Pipe fittings for conductivity probes with flanged boot, item 4 makes an 'o' ring seal to the body of a standard 12 mm diameter probe and has a 1/2" NPT thread. 
Item 5 is a shield to protect a submersible probe, it has a 3/4" FNPT thread to attach to a 3/4" MNTP pipe

Submersible conductivity probes
These electrodes are designed for continuous conductivity monitoring, either in a pipline or submerged in a tank. They are constructed with a 3/4" MNPT threaded ends for ease of installation. The probes include an integral resistance thermometer. The electrodes are platinum. The electrodes may be used to 150 psi.
