Coulometric Titrator by Karl Fischer's Method PE-9210 (generator electrode with diaphragm)

Coulometric Titrator by Karl Fischer's Method PE-9210  is designed for fast and accurate determination of moisture content in a wide range of products and materials in the liquid phase by coulometric titration. The titrator can be used in analytical and chemical technology laboratories, in control and supervision bodies. The device is most convenient for determining moisture in crude oil, heavy petroleum products, diesel fuel, transformer oil, etc. It can be used in laboratory and industrial conditions.

Features:
- The device is listed in the State Register of Measuring Instruments of the Russian Federation under the number 55135-13;
- The diaphragm cell is the best choice when analyzing samples with a water content of up to 1000 ppm. This design is recommended for the analysis of diesel fuels, transformer and turbine oils for the most accurate and reliable determination of moisture and minimizing the occurrence of side processes;
- The metal case, painted with chemically resistant paint, reliably protects the device from external influences
- Adaptive titration algorithm guarantees high accuracy when titrating samples with low moisture content
- The Windows Embedded Compact 7 operating system installed on the device allows you to save data in the usual Word and Excel formats;
- Graphical representation of the titration process;
- Built-in methodology for getting started quickly;
- The titration is started by pressing one button;
- Creation and storage of user's techniques in memory (up to 100 techniques);
- Storing measurement results in memory (up to 1000 series);
- Accounting for the reagent resource;
- RS-232/485 port for connecting scales and controlling external devices;
- 2 USB B ports for connection to a computer, laser printer, peripheral input devices (keyboard, mouse);
- The ability to use a USB flash drive (USB flash drive) to transfer and store data;
- Prompt, high-quality and inexpensive service support for our users;
