מד עובי אופטי 157 Series Optical Thickness Gauge
מד עובי אופטי Series Optical Thickness Gauge 157- BRISTOL
Thickness accuracy of ± 0.1 μm (± 0.004 mils)
Repeatability of ± 0.02 μm (± 0.0008 mils)
Reliable Accuracy and exceptional long-term repeatability gives you greater confidence in your thickness measurements.
The 157 Optical Thickness Gauge uses Bristol’s proven optical interferometer-based technology to measure the thickness of a variety of materials. Absolute thickness is measured to an accuracy of ± 0.1 μm and with a repeatability of ± 0.02 μm. This performance is guaranteed over long periods of time by continuously referencing every measurement to a built-in intrinsic standard of length. This ensures the most meaningful test results.
