New Asphalt Standard JTG3410-2025 Softening Point Automatic Tester

1、 Product Overview

New Asphalt Standard JTG3410-2025 Softening Point Automatic TesterIt is based on the H-ball method to determine the softening point of viscous petroleum asphalt. This instrument is suitable for determining the softening point of road petroleum asphalt, polymer modified asphalt, liquid petroleum asphalt, coal tar pitch distillation residue or emulsified asphalt evaporation residue. It is the preferred instrument for highway, bridge construction and research institutions. This instrument complies with the requirements specified in the People's Republic of China standard (GB/T4507-2014)<<Petroleum Asphalt Softening Point Determination Method>and the mandatory industry standard TG3410-2025<<Highway Engineering Asphalt and Asphalt Mixture Test Regulations>>T0606-2025<<Asphalt Softening Point Test>(new standard) of the People's Republic of China.

2、 Main features:

1. 4.3-inch LCD touch screen display: rich and centralized clock display, current temperature display, timing display, heating process display, test result display, function selection keyboard, etc., with high integration and simple operation. 2. Microcomputer CPU control, precise heating rate, meeting the requirement of 5+O.5C/min. The heating rate of the instrument is automatically calculated by the CPU based on the rate of water temperature rise per minute. After the test is completed, the equipment automatically displays and records the test results. 3. Laser scanning detection, when the steel ball falls, the instrument will automatically detect and lock the temperature of the steel ball falling to the bottom plate, and automatically calculate the average temperature, avoiding errors caused by manual calculation, making the detection data more accurate and the operation simpler. 4. The instrument adopts a German imported microcrystalline glass carbon crystal ceramic electric heating plate with magnetic stirring, and the temperature control method adopts glass blood bottom heating, which meets the requirements of the new industry standards. The instrument uses the PID intelligent control mode of the microcontroller to achieve the test requirement of a water temperature rise rate of 5.0

0.5C/min5、 The instrument has two testing modes, high and low temperature, which can be switched through settings. When the softening point is 80 ° C, water or purified water is required as the medium to reach and stabilize the heating rate at 50.5 ° C/min within three minutes. When the softening point is 80 ° C, glycerol is required as the medium to reach and stabilize the heating rate at 5+0.5 ° C/min. 6. The instrument has magnetic stirring function to ensure uniform water temperature in the glass dish, and the stirring speed can be adjusted. The instrument is equipped with a high-precision speed measurement device, which can display the speed of magnetic stirring (r/min) in real time.

7. Printing function: The instrument can be equipped with a printer, which can print the heating rate and test results throughout the entire test process after the test is completed. 8. Networking function: The instrument can be equipped with a network information transmission system, which can upload test information and results in real time through Ethernet cables, facilitating remote monitoring of the test process and results.
