Description

FEATURES:

  • Meets ASTM D 4414 “Standard Practice for Measurement of Wet Film Thickness of Organic Coatings by Notched Gauges” Standard used is traceable to NIST- All Aluminum – Size: 2-1/4 ” x 3-1/4″ x .034″
  • All aluminum construction
  • Double sided, dual scale
  • Gauge Range in Microns: 25, 51, 76,102,127,152,178, 203, 229, 254, 279, 305, 356, 406, 457, 508, 559, 610, 660, 711,762, 889, 1016, 1143, 1270, 1397, 1524, 1651, 1778, 2032
  • Gauge Range in Mils: 1, 2, 3, 4, 5, 6, 7, 8, 9,10,11,12,14,16, 18, 20, 22, 24, 26, 28, 30, 35, 40, 45, 50, 55, 60, 65, 70, 80
  • Press gauge into wet film at 90° angle and then withdraw; note the deepest tooth having paint on it and the next higher tooth that is not coated; true wet film thickness lies between these two readings

 

How to Use

  1. Place gauge on wet film at 90° angle
  2. Press into film
  3. Withdraw and note deepest tooth having paint on it and next higher tooth that is not coated
  4. The wet film thickness lies between these two readings
  5. Clean gauge in any suitable solvent immediately after use

Wet Film Indicator

Wet Film Indicator

The drawing indicates that tooth marked 3 mils is covered with the wet paint and tooth marked 4 mils is not covered. This indicates that the true wet film thickness of the material is between 3 and 4 mils thick.
