Gurley type Densometer | 158

Application(s): Air permeance testing of paper and board


The Gurley type Densometer measures the air permeability of paper and other materials. 

 

Transmit time (air permeability resistance) of 100cc and ISO air permeability can be displayed by automatically detecting falling rate of pressure cylinder.

Features & Benefits


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.

 

Eliminating variation between operators with constant-load sample clamp
If papers and board papers are tightened, their permeability will become larger. However, if they are
tightened with the force exceeding stiffness of the tester, the parameter will become lower. This tester
adopts a spring within the clamp table to make the tightening force even, eliminating test data variation
between the operators due to uneven tightening force.

 

Enabling easy and prompt sample clamping with the lever rotation of the sample clamp
Simple lever operations help the operators to mount and dismount samples.

 

Measuring comfortably with the oil gauge
The permeability will change depending on the amount of oil left in the cylinder. For example, the
permeability of high-quality paper decreases by approximately -1% under the oil level of -5mm. The oil
gauge enables the operators to monitor the oil amount left in the cylinder from outside, allowing them
to implement tests at ease
