NK9830 Semi-Automatic Kjeldahl Analyzer

The Kjeldahl method is a classic technique for determining nitrogen.

It is widely used for the measurement of nitrogen in soil, food, livestock, agricultural products, feed, and other nitrogen-containing compounds. The process for sample analysis using this method involves three main steps: sample digestion, distillation and separation, and titration

analysis.

Our company is one of the creators of the national standard GB/T 33862-2017 for "Fully (Semi) Automated Kjeldahl Nitrogen Analyzer." Therefore, the Kjeldahl analyzer series products we develop and manufacture comply with both the GB standard and relevant international standards.

One-button automatic operation: completes reagent addition, temperature control, cooling water control, sample distillation and separation, data storage and display, and completion notiffcation.

Control system: features a 7-inch color touchscreen, with English and Chinese language options for easy operation.

Dual-mode analysis: supports both automatic and manual analysis.

★ Three-level authority management: includes electronic records, electronic labels, and an operation traceability query system that meets relevant certiffcation requirements.

Auto shutdown: the system automatically shuts down after 60 minutes of inactivity, ensuring energy-saving, safety, and reliability.

★ Automatic result calculation: input the titration volume, and the system automatically calculates, stores, displays, queries, and prints the analysis results, providing partial functionalities of a fully automated product.

★ Built-in protein ratio lookup table: allows users to access and use it in system calculations.

Distillation time: adjustable from 10 seconds to 9990 seconds.

Data storage: can store up to 1 million records for user reference.

★ Anti-splash bottle: made from high molecular PP plastic, suitable for high-temperature, strong alkaline, and strong acidic environments.

★ Steam system: made from 304 stainless steel, with liquid level control using patented "separated capacitive liquid level sensor control," ensuring system safety, reliability, and long service life.

★ Condenser: made from 304 stainless steel, providing fast cooling and stable analytical data.

Leakage protection system: ensures operator safety.

Safety door and alarm system: ensures personal safety.

Digestion tube misalignment protection system: prevents injury from reagents and steam.

Steam system low-water alarm: prompts shutdown to prevent accidents.

Steam boiler over-temperature alarm and shutdown: prevents accidents.
