Features

Product Features

***Technology

Using adsorption process instead of conventional desorption process for peak area calculation completely avoids the testing error caused by incomplete desorption of samples at room temperature, and is very suitable for the determination of small specific surface area of ternary materials, graphite and other battery positive and negative electrode materials;(* * No. 2)

Dstable stability testing technology

Adopting unique Dstable stable testing technology ensures that TCD signals are not affected by changes in liquid nitrogen level during instrument testing, ensuring the repeatability and stability of test results.

Dcal automatic correction technology

Adopting convenient Dcal automatic calibration technology ensures that TCD signal changes during the instrument's lifecycle do not affect test results, ensuring the repeatability and stability of test results throughout the instrument's lifecycle.

Dtrap precise testing technology

The unique Dtrap precise testing technology is used to ensure that the control accuracy of TCD signals during the testing process reaches 0.1mV and is not affected by the environment, ensuring the accuracy of the test results.

Dsignal efficient testing technology

Using unique Dsignal efficient testing technology, single point BET testing results can be efficiently completed within 5 minutes, with a testing efficiency of up to 4 samples tested in 5 minutes.

Dctrl anti blow flying control technology

Adopting unique Dctrl anti blowing control technology, it avoids instrument air path pollution caused by sample blowing during the testing process, protects instrument operation safety, and extends the life cycle of the instrument.

Security protection mechanism

To ensure the safe operation of the instrument,
(1) Add a wake sensor to TCD to prevent dry burning, ensure the stability of TCD signals, and extend the service life of TCD.
(2) Develop a low-level monitoring program to monitor the operation status of the instrument, automatically control the instrument when there are abnormalities or other dangers, relieve the abnormal conditions that cause danger, and protect the safety of the instrument and operators.

Multiple Dewar flasks to choose from

High performance vacuum glass inner dewar bottle, customized and produced using self-developed technology, with both the insulation effect of glass inner liner and the safety performance of metal inner liner, not fragile;
High cost-effective vacuum glass inner Dewar flask with good insulation effect, capable of continuously testing more than 10 samples;
Metal lined Dewar flask, capable of obtaining accurate results with extremely high safety factor;

Visual display of operating status

The front panel of the instrument is equipped with a status display system, which displays the working principle diagram of the instrument. LED lights are added to each valve position to indicate the on/off status of the solenoid valve, allowing for intuitive judgment of the instrument's operation during the experiment.

Can be integrated and remotely accessed

The instrument communication interface is a LAN port, which can realize centralized control of one computer as the upper computer, and can remotely access and control the upper computer.

Independent degassing system

Equipped with a completely independent degassing system as standard, with two options of blowing and vacuum, the sample pretreatment is more intelligent, flexible, and convenient.

Software

software control

The newly developed DX 400 control software is an intelligent software that enables operation control, data collection, calculation analysis, and report preview on the Windows platform.

Real time calculation of test results

The adsorption process of each sample is dynamically displayed on the testing interface, with real-time display of adsorption peaks and real-time calculation of BET specific surface area for each sample.

Real time recording and storage of instrument control process

The Message window can switch display and record real-time instrument experimental control process and software manual operation information, making it convenient for engineers to analyze and remotely diagnose abnormal data.
