Automatic Kjeldahl Analyzer, CA-KJA-S06

Application

It is widely used in the fields of food processing, feed production, tobacco animal husbandry, soil and fertilizer, environmental monitoring, medicine, agriculture, scientific research, teaching, quality supervision, etc. to determine nitrogen content or protein content and cation exchange capacity.

Features

• The ultra-trace nitrogen content can be accurately tested to 10ppm.
• The Kjeldahl method is used:Digestion of samples in concentrated sulfuric acid environment, Steam distillation in alkaline environment, Boric acid absorption, Indicator titration endpoint color determination method.
• Fully automatic reagent addition, distillation, titration, titration cylinder waste discharge, calibration, liquid level monitoring, calculation, data storage, test report generation and upload, the entire experimental process is fully automated and simple.
• Fully automatic fault monitoring: safety door and digestion tube in place detection; the distillation generator has multiple protections such as pressure sensor, steam over-pressure protection, temperature sensor, temperature protection switch, water level float and potential dual detection; distillation distillate temperature and volume detection to avoid excessive temperature or distillation volume fluctuations affecting the test results; real-time monitoring of cooling water flow, low water pressure alarm, automatic termination of operation when water is cut off; condensate effluent temperature monitoring to ensure complete condensation of samples and accurate and reliable experimental results.
• Brand-new multi-core ARM operating system, 10-inch LED high-definition color LCD touch screen, real-time monitoring and display of experimental process.
• Double distillation mode, steam flow rate is adjustable from 0-100%.
• External titration cup, the experimental process is visible in real time, the titration system lighting configuration and mature color endpoint determination software are combined to minimize the impact of external light sources.
• High-precision titration system and professional integrated plunger ensure test accuracy and reliability.
• The titration system adopts dynamic titration technology and automatic speed titration technology. The titration system automatically detects and switches the titration speed, truly achieving the simultaneous completion of the distillation, titration and calculation processes, reducing the experimental time by 40%.
• The titration color can be calibrated automatically or manually. The titration endpoint is determined by using a high-precision 16-bit three-primary color digital signal color sensor to collect color signals.
• The instrument can store 100,000 sets of data, and the test results can be expressed in 12 ways, including Word and Excel.
• The pump body adopts polytetrafluoroethylene bellows pump: resistant to strong acid and alkali corrosion, excellent particle clogging resistance structure, stepper motor control, stable liquid addition. Negative pressure suction is safe.
• The splash-proof bottle is made of polymer material, which is resistant to high temperature and strong alkali, and at the same time ensures that ammonia does not leak and the recovery rate is not low.
• The liquid level in the reagent barrel is monitored to ensure that there is no lack of liquid during the experiment.
• The instrument has self-check function, one-keyreset, built-in operation assistant, and is more intelligent.
• There are 2 working modes as standard, and the nitrate nitrogen and high nitrogen automatic testing modules can be added according to needs.
• 304 stainless steel distillation reaction chamber, Teflon treated visual safety door.
• The distillation system specially designed according to the law of ammonia escape ensures high and reliable test recovery rate.
