Technical features：

1、Adopt high precision micro differential pressure sensor, accurate measurement results, good repeatability.

2、Large screen color touch screen display operation, Chinese and English interface menu-based operation.

3、The instrument adopts self-designed noise elimination device to control the suction fan, which solves the problem of high noise due to high differential pressure of similar products.

4、The instrument is equipped with a standard calibration orifice plate, which can quickly complete the calibration to ensure the accuracy of the data.

5、Testing method: fast test (single test time less than 30 seconds, fast results).

6, according to the test prompt, manually replace the test orifice plate, specimens using manual clamping device.
