Go Direct^® Chloride Ion-Selective Electrode (GDX-CL)
Specifications and User Guide

TROUBLESHOOTING
-Primary Test: Check the readings in the standards. The high should be around 1000 mg/L. The low should be around 10 mg/L.
-Secondary Test: Refer to General tips for using Ion Selective Electrodes (ISE).
