Máy phân tích nitơ Kjeldahl tự động KDN-390F là thiết bị chưng cất để tự động xác định nitơ trong mẫu, được thiết kế theo phương pháp Kjeldahl cổ điển. Thiết bị dễ lắp đặt và vận hành. Phép đo chính xác, sử dụng an toàn, đáng tin cậy, tiết kiệm thời gian và nhân công; màn hình màu 7 inch, thiết kế khởi động một nút, mức độ tự động hóa cao. Nó được sử dụng rộng rãi trong phân tích và xác định protein thô trong ngũ cốc, thực phẩm, thức ăn chăn nuôi, đất, phân bón, nước, trầm tích, hóa chất, sản phẩm sữa, sản xuất bia, tinh chế đường, dược phẩm, than đá, cao su và các chất khác. Đây là công cụ lý tưởng cho các nhà vận hành phòng thí nghiệm.

Product features:

l The body is made of engineering ABS plastic, which is beautiful, corrosion-resistant and never rusty.

l The imported chip integrated circuit control system is adopted to ensure the high quality and high standard of the instrument

l New operating system, 7-inch high-definition touch color screen, user-friendly design, simple and easy to understand procedures, so that experimental operators can easily master

l Fully automatic water replenishment, water addition, alkali addition, acid addition and distillation functions are completed by one key, providing safe and convenient operation.

l Automatically memorize the last parameter setting, which is convenient for operation and can be flexibly adjusted according to the detection requirements.

l Set start, pause and emergency stop functions, and flexibly control the experiment process to prevent emergencies.

l Working mode: hand in hand. One-button start in automatic mode; In manual mode, all functions can be started at the same time or separately without mutual interference.

l Receiving bottle bracket lifting system, before use or the last minute will automatically judge the program, automatic lifting, gentle movement process, safe and reliable, more in line with the national standard operation requirements, to ensure accurate test results.

l Each program has the functions of fault alarm prompt and automatic stop alarm after distillation, which improves the safety and convenience of the instrument.

l Double protection procedures of water shortage and overtemperature of the steam generator are adopted to prevent dry burning due to water shortage, and a high-sensitivity probe is adopted to stably control the required distilled water capacity and improve the use safety factor.

l Alkali supplement switch shall be designed within one minute after the start of distillation to prevent the sample from being scrapped due to too little alkali added to some samples.

l The splash-proof tube is made of high-performance acid-resistant and alkali-resistant materials at one time, which ensures the air tightness of the experiment, is not easy to age and prolongs the service life.

l The easy-pull glass safety door is simple and practical, and improves the use safety

l Water-saving function design, advocating the concept of green environmental protection
