ELECTRONIC SMOOTHNESS AND POROSITY TESTER

(Bendtsen Type)

SMOOTHNESS and POROSITY TESTER (Bendtsen Type) is a well established method for determining the surface roughness of materials ranging from news print for heavy fibre board. The Bendtsen method is also widely used foe air permeability tests for maximum user comfort and Convenience. Electronic Bendtsen tester is a powerful self contained units that sits right there in the lab bench, instantly accessible to perform the measurement, rapidly accuracy with reliable read-out of results. And noiselessly, without the traditional hardships of conventional Bendtsen testing, such as fluttering indicator and ever deffering levels when changing the rotameter tubes.

PRECISION AIR FLOWMETER: -

The electronic Bendtsen Tester uses an advanced high precision air flowmeter tranceduser, it is based on the thermal anemometer principle, where heated quartz sensing fiber in exposed to the air flow.
