Digital Automatic Penetrometer for Bitumen

Digital Automatic Penetrometer for Bitumen. Penetration value is measured by applying the needle with a load of 100 grams that vertically penetrates into the bitumen for 5 seconds at 25 degrees celsius. The amount of needle movement is the penetration value which is measured in tenths of a millimeter. The higher the penetration of the needle in the bitumen, the higher the bitumen grade.

Basic structure:

The digital display asphalt penetration tester is composed of a lifting mechanism for adjusting the needle, an electromagnetic release mechanism, a light source amplifier and an LCD display.


Performance feature:

1. The digital display asphalt penetration tester is equipped with a hand wheel, which can be used for coarse tuning or fine tuning of the needle, and is equipped with a light source to enlarge the observation.

2. The drop time of the needle can be switched by a time relay and is controlled by an electromagnetic release mechanism.

3. When operating, just press the "insert needle" key to complete the insertion procedure. Convenient and fast.

4. The needle penetration value is displayed by LCD, which is visualized and correct.
