​

TECH INC.’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
