The NADB-1005 Automatic Electronic Penetrometer determines needle penetration according to EN 1426, ASTM D5, and AASHTO T49 standards. The penetration depth of the needle is determined with a pulse-type electronic measuring system, which is separated from the plunger during the test. This allows the plunger's free guidance, which virtually eliminates friction during the test. Before each test starts, the measuring system automatically resets, and then the penetration needle moves down to the sample using the electric drive. The needle position can be finely adjusted using the joystick attached to the front panel. A magnifying glass and an ultra-bright LED lamp are supplied to assist the operator; the plunger is then automatically released onto the sample and raised automatically for the testing period.
The test result is displayed on the digital display. The plunger can easily be removed to calibrate its weight.
