China Penetrometer for Asphalt

Summary
This instrument is designed and made as per in and . It is used to determine the penetration of pavement petroleum asphalt, modified asphalt, liquid petroleum asphalt and emulsified asphalt. It is also suitable to test solid particle, powder, colloid and raw-food materials such as cheese, glycine, butter, cream and leavening. It can be widely used in food industry, highway engineering and other industrial fields.

I. Main technical features
1. The needle holder is designed novelly. It can be moved vertically and adjusted roughly and finely without measurable frication.
2. It adopts novel heating design. The heating and temperature measuring appliance is separated from water bath. Easy to operate.
3. Equipped with automatic temperature controller and high accuracy temperature sensor, the temperature can be set conveniently and control precision is high.
4. It adopts newly designed digital meter. The measuring data is stable and reliable.
