Product model: ZDJ-3S Origin: Beijing
【ZDJ-3SKarl Fischer Moisture TitratorInstrument Introduction: The fully automatic Karl Fischer micro moisture analyzer is jointly operated with Tsinghua University to control the speed through pulse width modulation; Automatically control temperature through proportional integral derivative and dynamic compensation methods; Real time display of temperature and speed level; It can be equipped with external heating devices and semiconductor refrigeration devices to meet experiments with special temperature requirements.
★ High precision standard piston burette and anti diffusion titration head ensure high-precision potentiometric titration. The push in design of the burette allows for easy and quick replacement at any time.
★ Mature technical services can provide various methods and technical manuals for instrument use, which can meet the needs of different users.
A well sealed titration cell separates the titration process from the outside world, and the automatic liquid supply and discharge system can automatically replace solvents or remove waste liquids, avoiding contact between chemical reagents and the human body.
A large and clear Chinese display screen can show titration curves, testing methods, data results, and statistical results, providing more parameter and analysis information, which is beneficial for improving work efficiency.
The Chinese monitoring software runs on the Windows platform and transmits data through the RS-232 interface to achieve remote operation.


【ZDJ-3SKarl Fischer Moisture TitratorInstrument features
According to the experimental environmental conditions, "automatic" or "manual" drift value background subtraction can be set to ensure more accurate analysis results.
The titration results can be output in the format required by GLP/GMP, and the stored titration results can be statistically analyzed.
★ Randomly equipped with titration monitoring software, which can monitor the entire titration process and perform version upgrades through the software.
★ The titration process is displayed in Chinese and can be input and output in both Chinese and English.
The titration table with a fully enclosed design can automatically change the solvent, avoiding contact between chemical reagents and the human body.


Optional accessories can be used for permanent titration.
