Performance characteristics:

1. The instrument adopts compression refrigeration and electronic heating technology, automatically adjusts the temperature of the inner and outer cylinders, automatically corrects the cooling coefficient, and is not affected by the external temperature.

2. The sample can be taken continuously for 24 hours, and the test results are more accurate and stable. The chip imported from the United States makes the instrument more stable and reliable. The test results are superior to the provisions of GB/T213-2008.

3. It is controlled by computer and adopts full-automatic system software, and can realize one-machine dual control or multiple control.

4. Automatic water injection, automatic drainage, no need to adjust the water temperature, just put the oxygen bomb into the cylinder, and the instrument can automatically complete all the test work.

5. It adopts advanced serial communication technology, integrates system control and data management, has good compatibility, adopts scientific and effective algorithms, has high data accuracy, stable and reliable system, and low failure rate.

6. The mixing motor adopts imported motor with more stable performance, which can ensure the stability of the instrument.

7. The machine can realize remote data transmission through software and can be used for office automation.
