HK-3140WS Micro Moisture Tester adopts Karl fischer coulomb electricity method with high sensitivity, high precision and low cost.It can be widely used in petroleum, chemical, power, pharmaceutical, commodity inspection, scientific research, environmental protection and other fields.

Summary of test Method

  1.1、An aliquot is injected into the titration vessel of a coulometric Karl Fisher apparatus in which iodine for the Karl Fisher reaction is generated coulometrically at the anode. When all of the water has been titrated, excess iodine is detected by an electrometric end point detector and the titration is terminated. Based on the stoichionmetry of the reaction, 1 mol of iodine reacts with 1 mol of water, thus, the quantity of water is proportional to the total integrated current according to Faraday’s law.

  1.2、 The sample injection can be done either by mass or volume.

  1.3、 The viscous samples can be analyzed by using a water vaporizer accessory that heats the sample in the evaporation chamber. And the vaporized water is carried into the Karl Fischer titration cell by a dry inert carrier gas.
