Note:

Paper dust meter

Product model: ZCA-1

Product use: The paper dust meter is suitable for the determination of dustiness of paper or cardboard. It is designed and manufactured according to GB/T1541-1989 "Determination of paper and cardboard dustiness ".

Technical Parameters

1 . Light source: 20W fluorescent lamp

2 . Irradiation angle: 60 °

3 . Workbench: effective area is 0.0625 m2 , can rotate 360 °

4 . Standard dust picture: 0.05-5.0 ( mm 2 )

5 . Dimensions: 420 × 350 × 250 ( mm )

6 . Quality: 8Kg

Operation method:

1. Sampling: cut more than 4 samples of 250mm × 250mm

2. Observation: Place one of the specimens on a rotatable table. Turn on the fluorescent lamp and check the visible dust on the sample surface under the fluorescent light. When viewing, the line of sight of the eye is kept at 250 to 300 mm, and different areas of dust are circled with different marks. The number of dusts of the same area can also be recorded according to the size of different areas.

3. Alignment: Rotate the table 90°. After each rotation, use the standard dust image to identify the area of ​​the dust on the sample. You can also mark the newly discovered dust according to different areas until it returns. The location to the beginning of Zui.

Standard configuration: host + contrast picture

According to the standard: GB/T1541-1989 "Determination of paper and cardboard dust"

Onsite Oxygen Cylinder Filling System

Oxygen Cylinder Filling System

With PSA principles, ETR oxygen cylinder filling system can produce 93%±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR oxygen plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.


Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
