Density Gradient Apparatus
Standards
ASTM D 1505
ISO 1183-1:2004
ISO 11542-2
Application
The density gradient apparatus is designed to determine the density of solid plastics with high precision, also can do quick comparation of the subtle difference of density of similar materials.
Compared with the immersion and the floating-sinking method, the density gradient method has the advantages of high measurement precision, easy operation and wide measurement range.
Technical Parameters
1. Measurement range: 0.80g to 2.70g/cm3
2. Accuracy: 0.0001 g/cm3
3. Density gradient tube: ID 50mm, length 900mm
4. Graduation range: 0-850mm, resolution: 1mm
5. Number of test stations: 3 (or more)
6. Temperature range: 20℃ to 30℃
7. Temperature accuracy: ±0.05℃
8. Standard glass floats: 0.80g to 2.70g/cm3, accuracy 0.0001 g/cm3
Features
1. Adopting high precision single-chip control method for temperature control, with heating and cooling system, stirring adopts split external drive internal spray stirring method, which not only ensures the temperature uniformity of ±0.1℃, but also effectively avoids the vibration of the temperature bath.
2. The inner liner body of the bath is made of highly transparent resin, with good thermal insulation, high transparency and strong anti-vibration.
