1. Fast: the infrared absorption method is used, the measurement speed is fast, and the time to test a sample is only about 400s; It can be loaded into 36 samples at one time for continuous measurement, and the samples can be inserted in the measurement, which is suitable for the analysis of a large number of samples.
2. Accuracy: high temperature combustion, oxygen combustion, to ensure the complete combustion of the sample and the full release of carbon, hydrogen, nitrogen elements, take effective measures to overcome the adverse effects of environmental factors, good repeatability, high accuracy.
3. Convenient: high degree of automation, by computer control to automatically complete the sample delivery, measurement, calculation results, no need for manual intervention; Can display, recalculate, save, query all results; With statistical function, it can easily obtain important data such as mean value, range, standard deviation and relative standard deviation of the result; When the computer is connected with the electronic balance, the weight of the sample can be directly transmitted, without manual input. The test data can be transmitted to the Internet through RS232 interface. No need to prepare chemical reagents and electrolytes.
4. Reliable: selection of high-quality components and materials, take a variety of anti-interference measures, with overtemperature protection, overload protection and leakage protection, the whole machine performance is stable, safe and reliable.
