Introduction
It is mainly used for quickly and accurately detect organic fertilizer and organic matter content in the material . Feature With quantitative heavy cough up potassium acid-sulfuric acid solution, under the condition of oil bath temperature control heating, make the samples in the oxidation of organic carbon, the remaining heavy cough up potassium acid with ferrous sulfate standard solution, titration, and silicon dioxide as the additive reagent blank calibration. According to the weight difference before and after oxidation oxidizer, titration device automatic processing, calculate the organic carbon content, multiplied by the coefficient of 1.724 in the instrument, and displayed on the screen the concentration of the organic matter in the sample percentage. Can put a long tube, 36, and boiled 18 elimination group samples (as a set of blank samples and sample, single titration). Technical parameters
1. A. organic matter content less than 3%, the parallel determination results error is 0.05%;
B. organic matter content is less than 3-8% of the parallel determination results error of 0.10-0.30%;
C. more than 15% organic matter content of the material, using solid dilution method.
2. Power supply: AC220V + - 10%, 50 hz + 1 hz
3. Determination of repeatability: parallel test results conform to the requirement of GB/T6423-94 index.
4. Cook power dissipation: 1 kw.
