Calibration and Use:
1. Connect Conductivity Electrode to BNC connector of an Epithelial Volt-ohm-meter (EVOM).
2. Generate the calibration curve for the electrode by using two solutions of known conductivities.
Characteristics:
1. This electrode consists of a pair of electrodes in 18 Gauge stainless steel tubing.
2. Each electrode contains a Ag-AgCl sphere for measuring voltage and stainless steel tubing for passing current.
3. The resistance of a solution or cell culture is calculated by using V=iR, where i is current injected, V is voltage measured, and R is resistance; hence conductivity equals the inverse of R.
Maintenance:
After each use, rinse the Ag-AgCl tip in distilled water and store dry.
