GDW-106 Transformer Oil Water Content Tester/Karl Fischer Coulometric Titrator
General Information
Coulometric Karl Fischer technology is applied to measure precisely trace moisture the measured sample contains.The technology is widely used for accuracy and cheap test cost. The model GDW-106 measure precisely trace moisture on liquid, solid and gas samples according to the technology. It's used in electricity, petroleum, chemicals, foods and so on.
This instrument uses powerful new generation processing units and brand new peripheral circuit and that the superior low power consumption make it capable to use small size storage battery and portable. Judging the electrolysis endpoint is based on testing electrode signal and the stability and accuracy are the vital factors of determination precision.
Features
1. 5-inch high-definition color touch screen, the display is clear and easy to operate.
2. Two methods of electrolyte blank current compensation and balance point drift compensation to revise testing results.
3. Functions of detecting measuring electrode open circuit fault and short circuit fault.
4. Adopts thermal micro printer, printing is convenient and fast.
5. 5 calculation formulas are built in the instrument, and the calculation unit of test results (mg / L, ppm%) can be selected as required.
6. Automatically save history records with time tab, maximum to 500 records.
7. Blank current microprocessor automatically controls compensation, and reagents can quickly reach equilibrium.
