Function and usage
It is used to test the trace moisture in solvent with high precision. It is operated simply and can
display the result directly in digits. GB-W type solvent moisture tester adopts the Karl Fischer
Volumetric Method to determine water in the tested sample. It is mainly used to determine the
moisture in solvent, paper, oil product, medicine, coating and other product. The instrument is
advanced with easy operation, and the testing data is reliable and accurate. Scope of application
Organic compounds: saturated and unsaturated hydrocarbon, acetals, acids, acyl-halides, alcohols,
stable acid radical, amide, weak amine, anhydride, bisulfide, lipid, ether halide, hydrocarbon
compound, peroxide, raw acid fat, salt and alkyl sulfide
Inorganic compounds: acid, acid oxide, alumina, anhydride, barium peroxide, calcium carbide,
cupric oxide, desiccant, hydrazine sulphate, and salt with partial organic and mineral acid.
Â· Display the measuring result directly in digits.
Â· Use the advanced integrated circuit and microcomputer control circuit
Â· Superimpose the alarm prompt function near the end point. When the titration is near the end point, the operators will get caution to decrease the speed of titration, and thus avoid the overflow so as not to affect the accuracy.
Â· Add the computing function. That is, key in the weight of the sample and the reagent consumption (normal water and sample consumption) and so on into instrument by keyboards. Press the percent age key, and the measuring result will be displayed on the digital display screen at once. Simplify the original complicated method.
Â· The appearance adopts the contact-mold type panel, the digital display indication, and keyboard dialog with attractive exterior and convenient operation.
