FBT-9 fully automatic surface area measuring instrument

FBT-9 Fully Automatic Specific Surface Area Tester Detailed Parameters

1. Product Overview: This instrument is improved based on the American ASTM204-80 permeability method. The basic principle is to use a determined amount of air to measure the resistance experienced by a compacted powder layer with a determined porosity and thickness. Widely used for the specific surface area of non porous powder materials such as cement, ceramics, abrasives, metals, and gunpowder

2. Main features:

1、 Users can freely adjust the porosity of the sample, and the measurement range is wider than that of FBT-5 type

2、 Users can also measure according to their needs Adjust the speed of the air pump by yourself

3、 The measurement accuracy has increased from four digits to five digits for FBT-5 type, expanding the range of sample measurement

4. The FBT-9 fully automatic specific surface area measuring instrument adopts a liquid crystal display screen, which is easy to display in Chinese

5、 Using trusted microcontrollers and integrated circuits, it automatically adapts to different temperatures, automatically detects the working status of the instrument, and ensures accurate measurement results

6、 Automatic detection of water level, automatic timing, automatic temperature measurement, automatic calculation and display of results

7、 Except for manual loading, the entire testing process is automatically completed to avoid human error

8、 Press the measurement button once to obtain a measurement result, which is easy to operate

III. Technical Parameters:

1. Diameter of the inner cavity of the breathable cylinder: 12.7 ± 0.1mm

2. Height of the sample layer in the inner cavity of the breathable cylinder: 15 ± 0.5mm

3. Number of holes in the perforated plate: 35

4. Perforated plate aperture: 0.1mm

5. Perforated plate thickness: 1 ± 0.1mm

6. Application range: Applicable to the range specified in GB8074-2008.

7. Measurement accuracy: relative error,

8. Temperature: 8-34 ℃

9. Voltage~220V ± 10%

10. Net weight: 3.2Kg. 4. Usage:

The usage and operation steps of this instrument can refer to the relevant provisions of "GB/T8074-2008 Method for Determining Specific Surface Area of Cement - Brinell Method"
