This instrument is fully computer-controlled, employs electronic photoelectric measurement, displays results on an LCD screen, and automatically prints test results using a miniature printer. It also features linear temperature heating, uniform bath stirring, the ability to test two samples simultaneously, and automatic detection of the sample's softening point. With a high degree of automation, it offers fast and convenient testing with reliable results, making it an intelligent instrument for testing asphalt softening points.

TD606 Series Asphalt Softening Point Tester

Model:TD606-2

I. Product Introduction

This instrument is designed and manufactured in accordance with the requirements specified in the Chinese national standard GB/T 4507 – Determination of Softening Point of Petroleum Asphalt, and the Chinese Ministry of Transport standard JTG E20-2011 “Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering”, specifically T0606-2011 – Softening Point Test of Asphalt (Ring-and-Ball Method). It is also produced with reference to international standards ASTM D36/D36M, AASHTO T53, EN 1427, ISO 4625 (Ring-and-Ball), and IP 59.This instrument is suitable for determining the softening point of various types of asphalt, including road petroleum asphalt, coal tar pitch, and liquid petroleum asphalt. It is the preferred instrument for asphalt production enterprises, highway and bridge construction units, and related colleges, universities, and research institutions.
