The Interchemical Thickness Gage, also known as IC or Inmont gage, has long been the standard for measuring wet film thickness in the coatings industry (U.S.Patent No. 3,128,558). It is ideal for thin film applications and used for measuring wet ink film at the press.
BYK-Gardner offers three basic models in various ranges: Model S - general use, Model R - rotating scale, Model L - Low inertia with rotating scale. All models have an accuracy of +/- 0.0001 in (2.5 μm) or 2.5% full scale, whichever is greater.


  • Very accurate for thin film applications
  • Can be used with moving surfaces
  • Easy to clean
  • Stainless steel construction for long life
  • Metric or mils version available
  • Compliant with ASTM D1212 and ISO 2808 methods
  • Gage holder optionally

The gage consists of an eccentric inner wheel, supported by two larger outer concentric wheels. At a specific point, the inner wheel touches and picks up wet film when the gage is rolled on the coated surface. This critical clearance may be read on a rotating scale.

The gages may be held between the thumb and forefinger to take a reading, or it may be inserted into the gage holder. This holder is widely used to measure coatings safely on moving surfaces such as high-speed press rollers. It can also be used on stationary, flat, or curved surfaces since the holder makes it easier to exert a steady, even force on the gage.
