Titrator ПЭ-9210 is designed for fast and accurate determination of moisture content in a wide range of products and materials in liquid, gas or solid phase by coulometric titration. The titrator can be used in analytical and chemical-technological laboratories, in control and supervision bodies.
The device is most suitable for determining moisture in crude oil, heavy oil products, diesel fuel, transformer oil, etc. It can be applied in laboratory and industrial conditions.

The device is included in the State Register of Measuring Instruments of the Russian Federation under the number 55135-13
