Constant Temperature Needle Penetration Tester LTNP-A10

Constant Temperature Needle Penetration Tester LTNP-A10 is designed and manufactured Penetration Tester conforms to ASTM D217 and D1403 international standards. It offers 0 to 700 taper degree measuring range and 0.01 mm resolution. It is mainly used to determine the needle penetration of bituminous mixture and cone penetration of lubricating grease (or petrolatum). It is also suitable to determine solid particle, powder, colloid a draw-food materials such as cheese, glycine, butter, cream and leavening.
