GD-2806G Automatic Asphalt Softening Point Tester

I. Summary
 The instrument is designed and made as per the National Standard of People’s Republic of China GB/T4507 “Test Methods for Softening Point of Asphalt”, and T0606 “Asphalt Softening Point Test (Ring and Ball Methods)” in the Industry Standard of People’s Republic of China. It is suitable to determine the softening point of highway asphalt, coal pitch, liquid asphalt and other types of asphalt, etc. It is the best choice of asphalt manufacture companies, highway and bridge construction companies, colleges and universities, and scientific research institutes.
 It adopts computer for controlling, electron photo-electricity for measurement, LCD for indication and Micro-printer for printing test data. It also has the characteristics of linear heating temperature, even stirring speed and it can make test for two samples at the same time and determine softening point of samples automatically. It is automatic, convenient and reliable, so it is an intelligent instrument for measuring softening point of asphalt sample.

II. Main technical specifications and parameters
 1. Power supply: AC 220V (-5%~+10%), 50 Hz;
 2. Measurement range:
  (1) For asphalt, the softening point of which is under 80 ℃, you can take distilled water as heating medium : +5 ℃~+80 ℃
  (2) For asphalt, the softening point of which is over 80 ℃, you should take glycerin as heating medium. +32 ℃~+160 ℃
 3. Temperature resolution: 0.01 ℃
 4. Stirrer: the stirring speed can be adjusted continuously.
 5. Heating rate: it will be adjusted to 5.0±0.5 ℃/ min automatically after three minutes
 6. Test result: It uses the LCD to show it and the printer to print it.
