Coulometric Titrator by Karl Fischer's Method PE-9210 (generator electrode without 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 non-diaphragm titration cell is very easy to operate when cleaned and filled with electrolyte, and its operation requires only one reagent (anolyte). Ideal for determining a wide range of water concentrations in samples (from 1000 ppm to 5%)
- 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;
