Kjeldahl Nitrogen Analyzer

I. Product Introduction

The semi-automatic Kjeldahl Nitrogen Analyzer is an instrument for determining nitrogen and protein content based on the Kjeldahl method. It integrates the originally manual distillation-to-condensation process into a single device that executes it automatically, considerably reducing the workload in testing.

II. Application Range

It can be widely used for the analysis of nitrogen and protein in food processing, feed production, tobacco, animal husbandry, soil and fertilizer, environmental monitoring, pharmaceuticals, agriculture, scientific research and teaching.

III. Executive Standard

GB/T 33862-2017 "Fully (semi-)automatic Kjeldahl nitrogen analyzer"

IV. Features

(1) Android 10 system with a 7-inch touch screen.

(2) Automatically completes liquid-adding steps such as adding alkali, boric acid, diluent and distilled water; automatically completes the distillation and absorption steps.

(3) Protective functions such as evaporation furnace water-level monitoring, anti-dry-burn protection, condensate flow-rate monitoring and condenser temperature detection.

(4) High 16 GB storage capacity, with a test-result storage capacity of 5 million records.

(5) Test results are in Excel format and can be copied directly to a USB flash drive.

(6) Test results can be printed and uploaded in batches.

(7) High-speed thermal printer; the test report is printed automatically once testing is complete.

(8) Wi-Fi networking; test results can be uploaded directly to the platform.

(9) Program-controlled switching of condensate water, saving water consumption.

(10) Condensate flow-rate monitoring with low-flow alarm.

(11) Multiple protections for evaporator water level, temperature and pressure.

(12) Strong corrosion-resistant components.
