TIM Tester Sample Positioning:
Convenient and Precise
Sample testing with the Analysis Tech TIM Testers involves the straightforward alignment of the circular sample within the concentric boundary line. But for the highest possible accuracy and repeatability, the Sample Positioning Fixture can be quite useful, particularly with type III samples (incompressible samples), The positioning fixture eliminates sample-position variation by providing a firm "corner" into which the test sample disks can be located with ease, consistently, each and every test.
Positioning without alignment fixture (type I and II samples) :

Positioning with the alignment fixture (primarily type III samples):

The positioning fixture also eliminates the problem of type III samples migrating with the initial application of the pressure when oil or grease is used to reduce the surface-contact-resistance.
The TIM Positioning Fixture is included with the TIM Accessory Pack.
