Smoothness & Porosity Tester (Bendtsen, Gurley)

Description:

A specialized laboratory instrument designed to measure the surface roughness (smoothness) and porosity (air permeability) of paper and board. These properties significantly affect print quality, coating uniformity, barrier performance, and overall product aesthetics. The Bendtsen and Gurley methods are industry standards for reliable, repeatable evaluation.

Use & Standard: Evaluates surface smoothness and air permeability of paper, board, and packaging materials as per IS 1060, TAPPI T460, ISO 8791-2, ISO 5636.

Laboratory Benefits:

1. Ensures optimal printability, coating performance, and product appearance
2. Supports material selection for packaging, printing, and converting industries
3. Provides essential data for process control and product development
