Performance features:

It has two structural forms, desktop and vertical, and can be freely selected according to the laboratory layout.

Large-capacity outer cylinder and water tank, with compressor cooling and heating functions to ensure constant water temperature and adapt to long-term continuous testing.

The quantitative water cup made of borosilicate glass with small volume change is used to ensure the stability of the water volume of the inner cylinder and the consistency of the test results each time.

Special oxygen bomb design (curved bottom), strong pressure resistance, shortened main period time.

The cooling calibration model is adopted to ensure the accuracy of the test results of high and low calorific value samples.

Automatic warning of sample weighing range; real-time monitoring of laboratory ambient temperature and humidity; automatic prompt of out-of-tolerance results.

Sample coding and weight information are automatically transmitted; test data can be backed up and uploaded; and experimental data is tamper-proof.

● It can achieve Orthrus management and record experimental process information.

Special features for fuel control:

1) If there are corruptive practices such as opening the lid and replacing the sample in the middle, the system will alarm and the experiment will be invalid;

2) Uploading data includes:

Environmental parameters: ambient temperature;

Process parameters: start time, ignition time, main period end time, main period temperature rise, cooling correction value C, etc.

Fault self-test: automatic lifting in place, automatic oxygenation in place, etc.
