158 | Gurley type Densometer Model G-B3C Gurley type Densometer is designed to measure air permeability in accordance to ISO 5635-5, ISO 9073-1 to 4 and 7, ISO 9092 as well as JIS P 8117, JIS L 1913. Applications are those in which 100ml of air permeates through their diameter of 28.6mm and whose permeating time is between 1.4 and 1,300 seconds. In particular, they are applications such as crepe, papers that exclude those showing air leaking from their surface if they are firmly tighten, including corrugated paper, and paper products made from paperboards. This tester is capable of automatically measuring permeability up to 9,999 seconds and also applicable to film sheet.

1. Automatic calculation enabled by high-precision detection with the optical fiber sensors This tester correctly detects and counts the scale of air permeability amount with the optical fiber sensors. At the measuring range from five ranges between 25 and 300ml selected by the operators, the accumulated time (s), air permeability resistance (s/100ml) and ISO permeability (μm/Pa ･ s) are automatically calculated and displayed. 2. Eliminating variation between operators with constant-load sample clamp If papers and board papers are tightened, their permeability will become larger. However, if...
