The DFRH-15B laser global method softening point tester employs advanced alpha temperature control technology, ensuring high-performance temperature control for the softening point tester!

The instrument fully meets the requirements of... JTG 3410-2025 "Code for Testing of Asphalt and Asphalt Mixtures in Highway Engineering" Asphalt softening point test requirements, oversized The LCD touch screen provides intuitive display of test data and heating curves. The system offers two methods for data acquisition: automatic detection via laser scanning and manual data entry. Its pioneering laser scanning technology ensures accurate recording even if the sample shifts out of position. The instrument can store over 100 sets of test results and heating curves, allowing users to retrieve and review test data and heating curves at any time. A built-in printer is also included. With the computer-based measurement, control, and analysis software, all tests can be conducted either directly on the instrument or via a computer; test data is automatically saved into a computer database. The instrument’s test results support real-time data uploading and can be integrated with terminal data platforms.

The instrument uses water or glycerin for testing and fully meets the temperature-raising requirements specified in the test procedures for both water and glycerin. It features high temperature resolution, a wide range of test temperatures, and automatic recording of test results, with the falling steel ball’s position displayed directly on an LCD screen. The instrument is easy to operate, boasts a sleek and attractive appearance, and includes a computer interface. Additionally, dedicated test analysis software makes the testing process even simpler and more accurate.
