KDN-19Y nitrogen analyzer Introduction: Based on the classic Kjeldahl nitrogen determination method, it is widely used for the analysis and determination of crude protein in substances such as grain, food, feed, soil, fertilizer, water, sediment, chemicals, dairy products, brewing, sugar production, pharmaceuticals, coal, rubber, etc. It has the characteristics of accurate testing, safety and reliability, and easy operation. The distillation device adopts an electric steam generator, which uses the heat energy of the heating tube to generate steam from the distilled water. The distilled water is automatically replenished and can continuously perform micro and constant distillation operations. characteristic: 1. Add a dual protection program for water shortage in the evaporator to prevent dry burning due to water shortage and improve the safety factor of use 2. Increase the overpressure relief protection of the evaporator to prevent electromagnetic valve failure and other factors from causing excessive pressure in the evaporator, resulting in bottle bursting, and improve the safety factor of use 3. Automatically add and replenish water, and the amount of received liquid can be adjusted freely 4. Water saving function design can save a large amount of tap water, advocating new concepts of energy conservation, emission reduction and environmental protection 5. The steam generator adopts all stainless steel electric heating tubes for heating and water level control, which are corrosion-resistant and durable, and automatically alarm for water shortage 6. Specific integrated circuit control systems can meet the safe use of different water quality in different regions, ensuring normal operation without replacing distilled water for a long period of time, saving a large amount of distilled water, reducing laboratory costs, and achieving the goal of fast, accurate, and low consumption 7. The splash proof tube is made of special high-performance acid, alkali, and heat resistant plastic, which has good sealing performance, stronger alkali resistance than glass, and a long service life Technical parameters: Measurement range: 0.1mg~240.0mg nitrogen; Sample quality: empirical value is 0.3-8.0g for solid and 2.0-30.0ml for liquid; Test accuracy: relative difference of 0.3%; Repeatability: Parallel deviation ≤ 0.2%; Measurement speed: 3-8min/sample Recovery rate: ≥ 99.5%; Condensed water control: water-saving design, automatic program control; Evaporator protection: dual protection against water shortage; Overpressure relief protection; Control mode: ship style switch Anti splash tube material: formed by strong acid alkali plastic mold; Power supply: 220V ± 10%, 50-60HZ; Rated power: 1700W; Dimensions: 412 × 376 × 740 (mm); Weight: 25kg;
