Automatic Digital Bitumen Penetrometer
Used to determine the consistency of a bituminous sample under fixed conditions of load, time and temperature. Penetration is expressed in tenths of a millimeter through which the standard needle penetrates vertically.
The penetration depth of the needle is determined with electronic measuring system, which is separated from the plunger during the test, this allows the free guidance of the plunger which virtually eliminates friction during the test.
The frame with levelling screws and spirit level consists of a digital control unit with touch screen, an anodised aluminum base plate with centering guide, magnifying lens and low voltage illuminator mounted on flexible arms.
At the start of each experiment, the measuring system is automatically reset. The cone is lowered so that the tip of the cone just touches the surface of the sample by pressing up and down arrows on the screen with fast and slow motion option. In this process, magnifying glass and led lamp help the user. The penetrometer allows the cone to free fall into the sample for the specific set time interval which can be set on display by user. Free fall time can be selected between 0 - 999 seconds. Using the joystick, the needle position can be adjusted precisely with the help of the magnifying glass and ultra-bright LED lamp on the device. The test result is displayed on the digital screen. 5 tests are made and the average is taken automatically.
Needle holder can be easily disassembled and reassembled for weight calibration.
The penetrometer is supplied with penetration needle, transfer dish and 6 penetration tins 55x35 mm dia.
Water Bath (with Cooling unit or without Cooling unit), Thermometer (IP38 or ASTM 17C or 63C) required for the test and the other accessories should be ordered separately.
Water bath dish with incorporated thermostatic coil, to be connected to the Water Bath. It keeps the temperature of the bitumen sample directly on the penetrometer, by avoiding to transfer it. Water bath dish should be ordered separately.
