For determination of the needle penetration according to EN 1426 - ASTM D 5 - AASHTO T49
20-2050 EN 1426 - ASTM D 5 - AASHTO T 49. Rigid frame with base plate and level gauge. The penetrometer arm is movable in height by a hand wheel with screw rod and is equipped with a manually operated plunger release. THe penetration depth is measured by a dial gauge 30 x 0.01 mm. Supplied with plunger 97.5 g, but without needles and other accessories.
20-2060 Similar to 20-2050, additionally equipped with automatically operated plunger release by a multifunctional timer, range 0.1 seconds to 99.99 hours. To set the penetration needle onto the sample surface a halogen lamp and magnifying glass, both with movable arms are attached. Supplied with dial gauge 30 x 0.01 mm to measure the penetration depth and plunger 97.5 g. Penetration needles etc. not included. 230 V, 50 Hz.
20-20660, Penetrometer, automatic, digital (see attached pdf)
20-20670, Automatic Digital Penetrometer for determination of the needle penetration according to EN 1426 - ASTM D 5 - AASHTO T49. At this the path a standard needle penetrates in the sample under standardized conditions(load, time, temperature) is measured. The penetration depth of the needle is determined with an electronic measuring system, which is separated from the plunger the influence to load and friction is virtually eliminated.
