Fischer titrator Expert-007M AP (coulometric)
Fischer titrators "Expert-007M AP" The Fisher titrator “Expert-007AP” is used for the quantitative determination of water in oil, petroleum products, natural gas, organic solvents, transformer oils, etc. GOST 24614, EN ISO 12937 (IP No. 438/01), GOST 24870, etc. They have a certificate of conformity with GOST R. Coulometric titrator with bipotentiometric and biamperometric indication of the titration end point (2 modes). Expert-007M allows you to determine micro amounts of moisture from ppm units according to GOST 24614, EN ISO 12937 (IP No. 438/01), etc. Objects of analysis: petroleum products, oil, natural gas, solvents for organic synthesis, transformer oil, washing powder, sugar, etc. Applications: chemical-technological, agrochemical, environmental and analytical laboratories of industrial enterprises and research institutions, control bodies, inspections. The operation of titrators is based on the K. Fischer reaction, which consists of a quantitative interaction in the presence of water of iodine and sulfur dioxide in a methanol-pyridine solution (Fischer reagent) with a high rate constant. Once the water is exhausted, the reaction stops and the increase in iodine concentration is detected by a bipotentiometric or biamperometric indicator system. The titrator automatically resets the results to zero after measurements. Titration occurs to a given point or throughout the titration blood. Saving measurement results with time indication in the device memory. Allows you to move the sample for a specified time. Depending on the object being analyzed, a choice of replaceable cells is provided. The device has a modern elemental database. Connection to a PC is carried out without additional material costs (software is included). The device software provides statistical processing of up to 10 measurement results. Evaluation of the correctness of the results and verification of the device can be carried out using distilled water. Scope of delivery: analyzer "Expert-007"; switching unit; coulometric cell; electrodes (set) - 3 pcs.; magnetic stirrer; calcium chloride tube; sample input port; power unit; PC cable; BY; documentation.
