The Asker CL150 Constant Load Durometer Operating Stand from Hoto Instruments features a unique pneumatic dampening mechanism that provides for improved repeatability and reliability in durometer testing.
- Works with Hoto Instruments High Performance Series X or Super EX Durometers
-
Test speed and weight are constant
-
Test speed is adjustable with air damper
-
Unique flexible joint system automatically aligns the presser foot to the surface of sample
The Asker CL-150 constant load stand eliminates the different speed and load variables which occur when testing samples with a durometer by hand. The test speed and load the durometer applies to the test sample is kept constant with air damper control and a standard weight. In addition, the unique flexible joint system enables the presser foot of the durometer to make perfect contact even on samples with inclined surfaces.
When an operator holds spring type durometer for measuring the hardness of rubber specimen by hand, the load applied from the durometer to the test specimen is not constant due to different pressure speed and force between operators. Therefore the durometer must be pressed to the test sample at the constant speed and force as far as possible. The Asker CL-150 Constant Load Tables eliminate such operator's errors. The data is then always reliable. Because applying speed and force of the durometer to the test specimen can be kept constantly by air damper control and weight which can be changed. In addition, the Asker CL-150 stand has a flexible joint system to make perfectly contact the presser foot of the durometer even inclined surface of the test specimen.
- The durometer's pressure force to the test specimen is always kept constantly by static load with weight.
- Pressure speed to the test specimen is also kept constantly by up- down lift with air-damper. And possible to change the lower speed by an adjusting knob.
- Even the test specimen with inclined surface, it is completely contactable with the presser foot of the durometer by flexible joint system.
- Available for 1000 g and 5000 g measuring pressure force in accordance with the type of the durometer required.
- Attachable for analog and digital Asker Durometer
