Description
Overview
GAOTek Digital pH and Ion Conductivity Tester ‘S’ series testers are equipped with a standard pH electrode (Circular glass bulb) used to measure the pH of non-viscous, non-high temperature liquids, e.g., tap water, drinking water, rainwater, etc. F series testers are equipped with a flat surface pH electrode used to measure the pH of semisolid substances, e.g., fruits, bread, creams, etc. The series testers are equipped with a long-reach pH electrode used to measure the liquids in the test tube. PH scan 40 tester is equipped with a standard BNC connector, which can use any pH electrode with BNC plug.
