The Microm II Metric Film Applicator is a casting knife film applicator with measurements in microns. Includes Teflon coated side plates, and a standard 400 series stainless-steel blade.
|Side Plate Options:
|Aluminum (Standard) or Teflon (Tefcrom)
|Stainless Steel (Standard) or Teflon
Micron Measurement - Used on the Metric Microm film applicator, each graduation on the Thimble Scale is 0.01 mm, the first visible number is 5 which is 5 graduations = 0.05 mm = 50 microns. One complete revolution is 50 graduations which is 0.50mm = 500 microns. The first increment on the Sleeve Scale is .50 mm = 500 micron, the second increment on the Sleeve Scale is 1 mm = 1000 microns, etc.
Before use, check the zero settings of the micrometers. Place applicator on a polished granite flat plate or alternatively plate-glass of suitable size. Set micrometers at zero. The blade should touch the glass/granite flat plate from end to end without the side plate being elevated. When the applicator is placed between the observer and a bright back light the user should see no light from beneath the blade and side plates. The zero point should check within ± 0.0005". If not, adjustment is required, place slight but constant pressure on the top support rods of the applicator with one hand. Rotate the micrometers so the blade is seated on the granite flat plate evenly from end to end and ensure no light is observed. Loosen the set screw on the top of the thimble on the micrometer, this will release the top thimble from the spindle. Align the zero mark on the thimble with the zero mark on the micrometer barrel and secure the set screw. Repeat if necessary to assure a proper zero is achieved. Cautionary Note: Make sure that there is no foreign matter such as iron fillings adhering to the blade magnets as this might result in improper applicator calibration.
