Penetrometer

Standard: ASTM D 6951-03 This portable hand operated equipment is designed to obtain a direct and rapid in-situ evaluation of the structural strength of road pavement layers constructed with unbound materials. The test is performed with continuous penetrations at approx. 800 mm depth with max. depth of 2 m by using extension rods.

It is suitable to make needle penetration determination for highway asphalt, modified asphalt, as well as residue of liquid petroleum asphalt or emulsified asphalt after evaporation. Standard : EN 1426, ASTM D5, AASHTO T49

Scope This instrument conforms to GB/T4509, GB/T269, ASTMD217, JTJ052-2000, T0604 and other related standards. It is suitable to determine needle penetration of asphalt and cone penetration of grease. The instrument can also be used to test food ingredients solid granules, powders, gels, body frozen and other materials, as well as cheese, sugar gum, butter, wheat its pouring, butter, fermented the like, in the food industry, highway traffic engineering and other industries department can be widely used. Features 1. It 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. It controlled by a computer, it can measure the 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. It has a computer communication port to communicate with a computer.
