Introduction: SYD-2801H penetration tester is based on the People's Republic of China national standard GB / T4509 "oil asphalt penetration measurement method", the People's Republic of China traffic industry standard JTJ052-2000 "highway engineering asphalt and asphalt mixture test rules" T0604 "Asphalt penetration test" in the technical requirements and the relevant provisions of the design and manufacture. The instrument is mainly used for the determination of road oil asphalt, modified asphalt penetration and liquid petroleum asphalt or emulsified asphalt evaporation residue after the penetration. The standard test conditions are as follows: Features: 1, set at home and abroad new penetration into the design concept of the culmination of advanced design, well-made, the advantages of filling. 2, can be used as penetration, cone penetration of two tests. 3, computer control, automatic completion of penetration, cone penetration of the test, LVDT by computer calibration technology to ensure accurate and reliable measurement. 4, lifting agency design novel, easy to adjust. 5, with automatic temperature control, magnetic stirring, water bath temperature uniformity, high precision temperature control. 6, LCD screen real-time display of various parameters. 7, with a micro-printer, print test results. 8, with a computer communication interface, can be achieved with the computer communication. Technical indicators: 1, the measurement range: 0 ~ 600 penetration. 2, the smallest index: 0.1 penetration. 3, into the time control device: Setting range: 0 ~ 99 seconds free set, the error: less than ± 0.1 seconds. 4, temperature control accuracy: 25 ℃± 0.1 ℃ (Note: the ambient temperature should not be higher than 20 ℃). 5, standard needle: 2.5g ± 0.05g. 6, standard cone: 102.5g ± 0.05g. 7, the heater power: 200W. 8, lifting regulation: sub-coarse, fine-tuning, easy to adjust freely. 9, memory function: can store 30 test data. 10, other: with a light source and magnifying glass, easy to use and operation; water bath thermostat device to choose from.
