Coating Thickness Probes

IS9560, IS9507+

For accurate results with formed cans, narrow tubes and aerosols

Innosen’s range of probes to accompany Sencon’s SI9600 Coating Thickness Gauge are designed for maximum ease of use and accuracy of results with flat sheets, formed cans, narrow tubes and aerosols.

If coating weight measurements suffer from a degree of variation, you have to err on the safe side when applying coatings in order to be sure that target weights are met.

Therefore a percentage of unnecessary coating is always being applied. With reliable measurements from Innosen’s coating thickness probes, the coating process can be brought under tighter control. Even a small reduction in coatings usage will quickly deliver a return on investment, saving money and raw materials.



The IS9560 is used with Sencon’s SI9600 Coating Thickness Gauge to measure the internal and external coating thickness on aerosols or long tubes with very small diameters. Instead of having to cut the tubes open and use the time consuming weigh-strip-weigh method, you can obtain instant results about coating distribution inside formed tubes and aerosols in a non-destructive and repeatable way with world-class R&R.


  • Thin carbon fibre arms that will go into the tube and remain rigid for precise placement.
  • Very small measurement surfaces to cope with the radial curvature of narrow tubes.
  • High precision electronics to process the very small signals involved.
  • A deadweight balance to apply the probe tips with careful but consistent pressure onto delicate tube walls.
IS9560 with probe

Extra small probe heads on the Formed Tube / Aerosol Probe are designed to fit into tubes from 13.5 mm diameter and up to 220 mm long (internal sizes).

NOTE: Due to the small measurement surfaces and the smaller signals involved, the Tube/Aerosol Probe must be used with a modified Sencon SI9600 Coating Thickness Gauge. Contact Innosen for details.



The Formed Can Probe is used with Sencon’s SI9600 Coating Thickness Gauge to test internal and external coating thickness on formed cans. The scissor action jaws are opened manually against spring pressure. Guide rings along the probe arms help the operator to move the can to the correct positions for testing. When the jaws are released, the spring release action applies a consistent and known pressure for each test, avoiding the risk of operator variability and ensuring accurate and repeatable readings.
