True Density Analyzer BUD-TD Series

Test Method

Static vacuum gas displacement/gas   expansion method (injection pressure method)

Analytical   Gas

High purity He, N2, Ar can   also be used

Total Constant Temperature System

The temperature of the test system is   uniform and stable, and the internal temperature variable of the instrument   is < 0.01°C

Sample   Analysis Station

1. standard sample pool   volume 20cm³

2. standard sample pool   volume 20cm³

Special specifications materials   customized exclusive sample pool: 1ml/10ml/50ml/100ml, etc

The multi-structure spinning   sealing method is adopted to ensure that the cavity space of the analysis   station is not affected by external twisting, and to improve the accuracy and   stability

Test Accuracy

Resolution  0.0001g/cm³，Repeatability  better than ±   0.5%，Standard     better than± 0.03%

Test   Time

A single group of analysis   station about 6 minutes, can also customize the analysis time

Pressure Detection System

Inlet pressure sensor

Vacuum   System

Equipped with vacuum pump,   using static vacuum extraction technology; The moisture adsorbed on the   surface of the sample is effectively removed and diffused into the air in the   sample pool, making the helium quantity more accurate

Gas Path Control System

The use of I-PID automatic variable dynamic   regulation technology, always maintain uniform pumping speed, improve   efficiency, effectively prevent sample spatter
