The new computer asphalt penetrometer is an asphalt penetration measuring instrument developed using advanced digital displacement sensors and microcomputer technology. The instrument meets the requirements of GB4509--84 "Petroleum Asphalt Penetration Measurement Method", ASMD5 --83/IP49--79 "Petroleum Asphalt Penetration Measurement Method" and TO60--93 "Asphalt Penetration Test". The instrument is simple to use, convenient, low-temperature drifting, has a wide range of applicable environments, realizes automation, digitization, and computerization of the test process, and provides a high-precision, good stability, and reliable performance for my country's highways, municipal administration, construction, petroleum and other fields. Computer automated asphalt testing equipment.Purpose:This instrument is mainly used to measure the penetration of viscous petroleum asphalt, viscous shale asphalt, liquid petroleum asphalt, and the residue after distillation or emulsification of asphalt materials. The penetration of asphalt is the depth to which a standard needle attached with a certain mass penetrates vertically into the sample under specified time and temperature. Feature：1. It can perform three consecutive tests and automatically calculate the average test value.2. System test mode allows sensor detection and recalibration.3. The instrument working platform can be adjusted horizontally up and down within 0~20mm.4. The penetration needle bar can be manually adjusted up and down.5. Automatic prompt when the sensor exceeds the measuring range.6. The test time can be set to 000.0------999.9S.Technical Details:-Time Setting - 5-30s Max needle penetration - 500 Displace measure range - 0-30mm Measuring accuracy - ±1%(0 - 10mm); ±10%(10.1 - 30mm) Standard needle - 2.5±0.05g Sample vessel dia. - 70mm Power supply - 220V 50Hz Gross weight - 10kg
