Ⅰ. Purpose

GD-2801I Automatic Penetrometer for Petroleum Asphalt is designed and made as per the National Standard GB/T 4509 and T0604.

The automatic asphalt penetrometer is suitable to determine the needle penetration of petroleum asphalt, modified asphalt, liquid petroleum asphalt, and residues after evaporation of emulsified asphalt.

Ⅱ. Characteristics

1. GD-2801I automatic asphalt penetrometer integrates new design concepts about penetrometer all over the world. It is advanced and delicate.

2. It can make determination for needle penetration and cone penetration.

3. Controlled by a computer, it can make determination for needle penetration and cone penetration automatically. The test data are accurate and reliable.

4. The newly designed up and down assembly can be adjusted freely.

5. Equipped with automatic temperature controlling device and magnetic stirrer, so the bath temperature is uniform with high temperature controlling accuracy.

6. All parameters are shown on the LCD in real time.

7. Equipped with a micro-printer, so it can print out test data.

8. This automatic asphalt penetrometer has a computer communication port to communicate with a computer.

Ⅲ. Technical parameters

1. Measurement range: 0~600 penetrations;

2. Resolution: 0.1 penetrations;

3. Timing selection: 0~60 s; Timing error is less than ±0.1 s;

4. Heating power: 200 W;

5. Temperature controlling accuracy: 25±0.1 °C; (The ambient temperature should not be higher than 20 °C);

6. Data storage: 30 groups;

7. Constant temperature bath: made of harden glass;

8. Stirrer: a magnetic stirrer;

9. Standard needle: 2.5±0.05g; as per GB/T4509, and T0604.

10. Up and down holder: it contains fine adjustment and coarse adjustment assembly to let needle tip just contact with sample surface;

11. Power supply: AC 220V±10%, 50 Hz.

12. Memory function: it can save 30 groups of test data.

13. Others: Equipped with light source and a magnifier, so it is convenient to be operated; the thermostatic device in the water bath is optional.
