Máy đo độ dày lớp phủ Sanko SP-1100D
The SP-1100D is provided with not only the general characteristics as the electromagnetic type but also the unique construction with which perfect constant pressure contact can be obtained to measure the thickness of plasticity film such as resist and screen etc. in screen process, specially.
- The tip of the electrode has a gentle curvature.
- The arm of the probe can be loaded with the weights.
- The probe unit can stand independently with 2 electrodes and 1 support leg.
When iron is moved toward or away from a steel core coil which carries electric current, self-inductance increases or decreases in accordance with distance.
This change in inductance can be utilized to measure the thickness of non-magnetic surface treated film (D) on iron substrate.
The thickness of non-magnetic film, non-conductive film and resist film etc. applied or placed on iron substrate can be measured.
