3、Product features

1）The shell of the test box is sprayed with plastic, that is, we often say electrostatic powder spraying method, which makes the appearance of the case excellent, strong mechanical strength, corrosion resistance and no rust.

2）Adopt semiconductor three-stage refrigeration technology, good refrigeration effect and stable data.

3）Use the digital display to control the required test temperature, and display the temperature value of the temperature measuring point in real time.

4）The operation process of the test is convenient. The test equipment can not only be used in the test room, but also be tested on site.

5）There is no need to use volatile dry ice for testing, so the finished products are cheaper.

6）The probe in the equipment and the refrigeration unit can be completely separated, which is convenient and practical and not restricted by the direction of the specimen.

7）Pt100 temperature probe is adopted for high measurement accuracy and accurate data.

8）Pressure and corrosion resistant rubber tubes are used for liquid circulation to increase the service life of dew point meter.

9）temperature value control using microcomputer temperature control PID adjustment technology, high temperature control precision, high temperature stability.

10）high safety performance, in the design process of the circuit and refrigeration cycle independent, so that the electrical part of the equipment is not affected by the liquid cycle, so as to ensure the stability of the electrical part of the collection of data.

11）Integrated power supply, cooling, circulation and control system, realizing the whole process of automatic control.

12）During the test, the working face of the probe is in contact with the specimen, and the working face of the probe can be in any direction.

13）The test process can be carried out according to the detailed product specifications. The whole experiment is easy to learn.
