GD-2122B Automatic Water Content in Petroleum Product Tester

Purpose :

  GD-2122B Automatic Coulometric Karl Fischer Titrator/Moisture Meter is designed and made as per the National Standard GB/T11143 "Test Methods for Water Content of Liquid Petroleum Products (Karl Fischer Methods)".  GD-2122B Automatic Coulometric Karl Fischer Titrator/Moisture Meter is suitable to determine water content in the liquid petroleum products by titration using Karl Fischer reagent. Adopt a microprocessor for control, so it has characteristics of rapid determination speed, high precision, LCD display, and automatic print. It also has function of self-diagnostics, menu selection. It is a multifunctional, convenient, and automatic analysis instrument.
