The spacious LCD display screen is easy to read titration methods and related information, and can display real-time curves to follow the titration process. After the titration is completed, all data can be automatically saved and processedUSBCopy the interface toUIn a disk or computer. Built in magnetic stirrer, fully sealed titration container, reducing the impact of environmental humidity on the results. The replaceable burette is convenient for changing the titrant at any time, and the built-in air pump can replace the organic solvent in the titration beaker in just a few seconds, saving experimental time. The instrument can be connected to keyboards, scales, and printers、 USBstorage device、 PC、VGAExternal devices such as monitors facilitate data transmission, software upgrades, improve your work efficiency, and strengthen laboratory data management HI903 Karl Fischer Moisture AnalyzerIt is an automatic titrator with flexible functions that can accurately measure the moisture content in samples. It can automatically add titration standard solution and detect the endpoint of titration reaction with dual platinum needle electrodes. The instrument is equipped with multiple moisture analysis methods, including different types of samples, and can store up to instrument methods and user-defined methods100It can be used in fields such as food, beverages, cosmetics, chemicals, pharmaceuticals, petroleum and petrochemical manufacturing.
	Dynamic titration function The dynamic titration function allows the titrator to adjust the titration volume based on changes in MV values, resulting in more accurate results. This provides a larger dose near the start of titration and a smaller, more precise dose near the endpoint of titration. Offset [drift] compensation HI903Karl FischerVolumetric methodThe titrator can automatically adjust the titration calculation to take into account the influence of any environmental humidity entering the titration cup. By correcting for water that does not exist in the actual sample, this provides more accurate results. Average value of titration results The continuous measurement results of the Karl Fischer titration instrument can choose the average of multiple measurement values. Titration information storage and preservation HI903The Karl Fischer titration database can store information on 20 types of titrants, which can remind users to calibrate the concentration of the standard solution at regular intervals and reduce measurement errors. Optional endpoint mode HI903SelectHI76320The dual platinum needle polarized electrode automatically detects the endpoint, and users can choose the MV value based on the mV stabilization time or drift rate. Pre titration process The pre titration process can eliminate solvent and residual moisture in the beaker, and can keep the solvent dry in standby mode.
Burette and measuring system
	Precision metering pump Our unparalleled40,000The piston driven pump can conveniently add extremely small and high-precision titrants or reagents. Chemical resistant pipes The suction and separation pipes are made of durable and chemically resistant materialsPTFEMade and equipped with a light blocking polyurethane jacket to protect the photosensitive reagent. Unique burette* Specially designed anti diffusion burette , specially designed glass burette , can accurately deliver titrants to high turbulence mixing areas, ensuring rapid reaction; Prevent the titrant from diffusing into the solvent in the beaker.
Titration and solvent system
	Efficient sample processing HI903Equipped with a quick sample port and replaceable rubber spacer, the sample can be quickly added to the solvent in the beaker through the movable partition on the titration container cover. The integrated magnetic stirrer ensures uniformity, thereby achieving accurate and rapid reactions. Chemical resistant titration container Glass and PTFE titration cups and accessories are designed to withstand the harsh solvents and reagents involved in Karl Fischer titration. Sealed solvent system The titration container is completely sealed,Keep the system dry and reduce the consumption of titrants, while saving time between titrations,Prevent moisture in the environment from affecting experimental results. The solvent can be replaced within seconds without opening the titration container. Color developing desiccant Colorable and reusable silicone desiccants can be used to determine whether replacement is necessary based on color changes.
