2025 new standard computer asphalt penetration tester softening point tester

1Instrument Introduction

1. Overview:

The 2025New standard computerized asphalt penetration testerIt is an instrument developed using excellent grating digital displacement sensors and intelligent microcontroller circuits to measure the penetration of asphalt needles. The instrument is based on the transportation industry standards of the People's Republic of ChinaJTG3410-2025In the "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering"T0604-2025Asphalt penetration test, standard of the People's Republic of ChinaDesign and manufacture according to the requirements of GB/T4509-2010 "Determination of Penetration of Petroleum Asphalt" and ASTMD5-95 "Determination of Penetration of Asphalt".The instrument complies with national standardsGB/T4509-2010、Ministry of Transport's Traffic StandardsJTGT0604-2025、National MetrologyJJF1208-2008 and American standard ASTMD5-2006Specification requirements.

2. Characteristics:

（1）New standard computerized asphalt penetration testeradopt4.3Inch LCD touch screen andCPUSingle chip microcontroller control has improved the integration level of the instrument, making operation simpler and clearer; Implemented automation, digitization, and computerization of the experimental process;

（2) The instrument adopts a new type of grating displacement sensor,Compared to other displacement sensors, it has higher anti-interference performance, improving the stability of the instrument and enablingNeedle penetration accuracy measured by instrumentsmore precise.

（3) The instrument design adopts a single heat temperature control device system, which controls the equipment water temperature at 2 ° C when the room temperature is lower than the test temperature (room temperature -5 ° C)5℃±0.03At around ℃, it can effectively increase the measurement accuracy of the experiment and the ease of instrument operation.

Based on the above characteristics, our company has designed a new type of penetration tester that provides a high-precision, stable, and reliable computerized asphalt testing instrument for the fields of highways, municipal engineering, construction, petroleum, and other industries in China.
