This apparatus is designed according to the national standards GB/T
4509-1998/2010, it mainly used to determine the asphalt needle
penetration and petrolatum conical penetration. It’s widely used in
food industry, road engineering, and many other industries.
Advanced mechanical design, easy regulation of lifting; digital
type temperature control meter, accurate temperature control, high
precision needle penetration digit meter guarantee the reliable
results. Advanced machinery design, easy lifting regulation,
digital temperature meter, accurate temperature control, high
accuracy needle penetration tester guarantee the reliable test
- Digital indication of needle penetration value
- 6 steps of penetration timing device, high control accuracy
- Coarse / fine regulation on lifting frame, easy regulation,
accurate needle aligning.
- Equipped with grease smasher, constant temperature bath, automatic
control of water bath, multifunction, highly cost effective.
- By choosing standard needle, specimen plate, thermometer, weights
can do some different test.
