Description
PMI’s Envelope Surface Area Analyzer (ESA) offers a simple, fast, and reliable technique for external surface area measurement – a measurement not readily achieved by static nitrogen adsorption (BET) methods. The ESA’s innovative use of flow permeametry combined with its sophisticated self-adjusting viscous-flow controller enables testing of a wide range of powders and other samples, including materials with surface areas of only several square meters per gram.
- Uses nitrogen or other noncorrosive gases; no expensive gas mixtures required
- Windows-based software handles all control, measurement, data collection, and report generation; manual control also possible
- Compatible with Windows XP or higher
- Real-time graphical test display depicts testing status and results throughout operation
- Nondestructive testing
- Length of test approximately 5 minutes
- Wide range of acceptable sample types and sizes
- Minimal maintenance required
