NBA 450 Automatic RING & BALL

Description

Reliable and entirely automatic, the NBA450, scaling from 0 to 200°C, determines the softening point of bitumen, resins, waxes… with the help of an optical cell. In order to do this, 4 predefined methods are installed with a storage capacity nearby 320Go, authorizing the introduction of your own methods.

Measurement principle:

  • A sphere with known mass is loaded onto the sample contained in the ring.
  • At the beginning of the test the sample is solid.
  • The sample is heated at constant rate (4°-5°C/min)
  • The temperature of softening at which the ball can drop to certain height it is marked as the softening point.

Based on the expected temperature of softening point three different liquid can be used:

  • distilled water range +30°C – +85°C
  • glicole range +30°C  – +110°C
  • glycerin range +80°C – +175°C

The NBA 450 is completely controlled by a touchscreen display and is equipped with 2 indipendent measuring cell with higly security standard.

Security and maintenance

  • Sealed resistance easy to clean
  • Overtemperature protection
  • Marchio CE

The temperature sensor calibration it is easy and executed through the software.

The liquid stirrer is done by a mechanical stirrer not magnetic efficient with viscous liquid.
