Infitek Automatic Kjeldahl Analyzer, KJA-P2800

Application

It is widely used to detect the overall content of ammonia nitrogen and protein nitrogen in grain, oil, food, dairy products, beverages, feed, soil, chemical fertilizers, drugs, sediments and chemical products. It is an important physical and chemical analysis instrument for product quality inspection.

Features

Accuracy

• Color determination method: Reliable three primary colors of red, green and blue are used, with three curves, standard acid amount and protein (nitrogen) content displayed in real time. It helps users to monitor the distillation, calculation and titration process in real time.
• Intermittent alkali addition ensures that the acid-base reaction is controllable to avoid the escape of ammonia caused by violent acid-base reaction in the absence of steam.
• True uninterrupted distillation: Constant steam, uninterrupted steam during water replenishment to ensure smooth vaporization of ammonia.
• Adjustable distillation power: ensure good recovery of low concentration samples.

Safety

• It has the function of real-time detection and control of the temperature of the distillation flask. If the temperature is too high, the instrument will automatically stop heating.
• It can automatically detect pressure sensor, cooling water flow and water pressure in real time and alarm.
• The distiller adopts double liquid level control (double safety). If the distillation flask is short of water, the instrument automatically stops heating to prevent the distillation flask from dry burning.
• It has the safety door status and digestion tube in-place monitoring function to prevent accidents.

Convenience

• Built-in test plan: it can be directly retrieved from the instrument database to efficiently complete the testing tasks without writing it into the database again.
• Automatic acid addition, automatic alkali addition, automatic dilution addition, automatic distillation, titration (distillation and titration are carried out at the same time), automatic storage, automatic printing, calculation results, automatic recording of all analysis data.
• Optional data transmission function: sample data, weight results, batch information and analysis results can be uploaded to the computer via USB or wireless transmission system.Automatic recording and data uploading can significantly reduce the risk of error, realize full traceability of sample parameters, and ensure that all data is safely stored on the computer for future reference, report and audit.
• Optional permission classification function can realize data traceability management.

 

Beautiful Appearance

• The whole instrument is made of ABS engineering plastics: it has the characteristics of corrosion resistance, long life, high strength and excellent insulation performance.
• Pipeline corrosion resistance: corrosion-resistant pipes are used inside the instrument.
