D50 Dumas Nitrogen Analyzer Introduction
Protein is one of the six major nutrients for human and animal survival. It is the material basis of all life. Nitrogen is one of the three major nutrients for plant development and growth. The Haineng D50 Dumas Nitrogen Analyzer can quickly detect samples. Protein/nitrogen content, no need for pre-treatment, shorten the detection time to 3 minutes; the whole experiment process does not use or produce any toxic chemicals, safe and environmentally friendly; built-in autosampler, no artificial intervention, automatic data processing , high degree of intelligence, and effectively improve work efficiency. Features
• Self-diagnosis warning, 23 kinds of fault diagnosis methods are built in the instrument. If the experimental conditions are not available and the status is not ready, the operator will be prompted in time by alarm.
• Fixed cycle maintenance reminder, based on the data characteristics of the sample, quantity, oxygen consumption and other relevant data information, analyze and judge the use of consumables, determine the replacement time and cycle of consumables, and promptly remind the operator to replace consumables.
• Standby/Wake-up function, the Dumas Nitrogen meter needs a certain period of time to stabilize the work after warming up, in order to reduce the efficiency reduction caused by frequent switching machines, the standby wake-up function is added, and the instrument maintains a constant temperature in the standby state. When you wake up, you can quickly return to work.
• The instrument automatically collects weighing data without manual input, saving time and avoiding human error; it has adjustable size synchronous display window when collecting weighing data, and has voice report verification function, so that the operator can stay away from the instrument. On the balance, the sample weighing is automatically input and the data can be verified by means of display and sound. When the instrument is sampled, the next batch of sample weighing data can be collected simultaneously without affecting the normal experimental process of the instrument sample.
• Intelligent oxygen addition function, the software adds oxygen according to different conditions and reduces the consumption of reducing agent.
• With overpressure isolation to ensure the safety of users and instruments;
• The burner has a safe low voltage, over temperature alarm power off function, and the operation is safer.
Convenient feature
• The software has automatic and manual air leak detection function, which is convenient for the operator to check the instrument after replacing the consumables;
• Real-time display of gas flow, burner and detector temperatures, detector values and pressure monitoring data;
• Built-in expert method library, the user can directly select the corresponding experimental method to sample analysis, easy to operate, and users can edit and save methods according to their own needs;
• Customizable functions such as the format, unit name, and unit logo of the experiment report;
• Data Processing: The software has RSD and average calculation capabilities.
Economic characteristics
• Use carbon dioxide as a carrier gas to save on experimental costs;
• The use of Peltier-metal condenser to remove water, high water removal efficiency, can save the consumption of chemical water removal agent, saving experimental costs. Technical Parameters
