GAOTek Digital Water Calcium Hardness Tester

GAOTek digital water hardness calcium tester is used to detect calcium and magnesium ions in water

GAOTek-HTR-279

Description

Overview

GAOTek digital water hardness calcium tester is used to detect calcium and magnesium ions in water. It’s an electrochemical sensor called an ion-selective electrode that measures ion concentration using membrane potential. When it touches the ion-containing solution, it connects with the sensor at the membrane-solution interface. This electrode is selective, responding to specific ions according to the Nernst formula. It’s known for its selectivity and quick equilibrium time, making it a popular choice for potential analysis.

 

Features

  • Round bulb, large sensitive area, fast response, stable signal
  • PP material
  • The lead is made up of pure copper
  • Can directly realize remote transmission which is more accurate and stable than the lead signal of copper – zinc alloy
