KDN-19A volatile base nitrogen analyzer Introduction: KDN-19A is mainly used as an instrument for the determination of volatile base nitrogen. Volatile base nitrogen is an important indicator of the freshness level of food in meat, fish, and eggs, and is also an important indicator for detecting the fermentation status of raw materials during mushroom cultivation. Compared to the semi micro nitrogen determination method commonly used in national standards, the automatic Kjeldahl nitrogen analyzer method has a very simple distillation and nitrogen determination process, which can avoid repeated cleaning of the reaction tank. Our company's KDN-19A model is an instrument for detecting volatile base nitrogen, which is more in line with experimental requirements to avoid performance waste. A sample takes about 5 minutes and is suitable for the determination of large batches of samples. The results have good precision, accuracy, high recovery rate, and the method is simple. Features: 1. Microcomputer chip control, digital display of distillation time, and countdown function, more intuitive and clear. 2. Add a dual protection program for water shortage in the evaporation furnace to prevent dry burning due to water shortage and improve the safety factor of use; 3. Add overpressure and pressure relief protection for the evaporation furnace to prevent excessive pressure and bottle explosion caused by electromagnetic valve failure, and improve the safety factor of use; 4. All internal components of the instrument have been comprehensively upgraded, with a 25% improvement in work efficiency compared to the previous generation and a longer service life; 5. To remove the receiving bottle one minute in advance, a new receiving bottle bracket is added, which is clean and orderly, enhances the customer's experience of use, and is closer to the national standard operation; 6. Detection end alarm reminder; 7. Water saving function design, through program control, the condensate water is synchronously opened during sample testing, and automatically closed after testing, advocating a new concept of energy conservation, emission reduction, and environmental protection; 8. The thin film lightly touches the button, providing a comfortable feel and a simple and refreshing panel; 9. Automatically memorize the data set for the next time, suitable for distillation with different requirements; 10. The splash tube is made of high-performance acid-base and heat-resistant plastic, with good sealing performance and extended service life; 11. Prevent reverse suction of receiving and digestive fluids, ensuring testing quality and safe use; Technical parameters: Sample mass: 10g Detection accuracy: relative difference of 0.3% Repeatability: Parallel deviation ≤ 0.2% Recovery rate: ≥ 99.5% Measurement speed: 8min/sample Condensate control: water-saving design, automatic program control Control method: Film touch button Evaporation furnace protection: dual protection for water shortage, overpressure relief protection Alkali adding method: Anticorrosion pump is injected at a fixed time Distillation method: timed distillation Material of anti splash tube: strong acid and alkali resistant plastic mold, one-time molding Display method: digital display Power supply: 22V ± 10%, 50-60HZ Rated power: 1800W External dimensions: 412x376x740 (mm) Weight: 25kg
