Asphalt infrared spectrometer

The instrument is designed and manufactured in accordance with the requirements of T 0673 "SBS content determination test" standard added in JTG E20 "Test Rules for Highway Engineering Asphalt and Asphalt Mixture" and the relevant provisions of JT/T 1177 "Modified Asphalt SBS content tester" standard. The instrument adopts Fourier transform infrared spectrum analysis method, which can quickly, accurately, safely and reliably determine the content of SBS in modified asphalt. It is an ideal instrument for the production, research and use of asphalt mixture to detect the content of SBS in asphalt.

Main technical features

1. The instrument has powerful software functions, self-diagnosis function, can handle standard peak, peak area integration, baseline calibration and other functions as well as infrared control, spectrum processing, data conversion, multi-component quantification and other operations.

2. The instrument has automatic and intelligent operation functions, automatically retrieves samples, and can directly issue the SBS content of the tested sample in a few seconds, which is fast, accurate, and worry-free.

3. The instrument has an intelligent humidity automatic reminder device, automatic digital display of humidity software, automatically reminds the user to replace the desiccant, solves the hidden dangers in the infrared use process, and can also reduce the user's maintenance cost and intensity.
