Gardco Type IC Precision Gauge

Wet Film Thickness With Center Eccentric Disk

Skinny IC Gauge

The "Skinny" IC Gauge

Aside from the standard 2.00" diameter x 0.640" wide gauge, there is the new "skinny" version for narrow substrate measurement.  It has a width of only 0.250 inches with an eccentric wheel width of 0.0625".

Standard IC Gauges
Meets ASTM D1212, D3794

These gauges are similar in design to the original Interchemical gauges patented about 1950, with the distinction of having dual scale in mils and microns with a center eccentric disk.

 

 
Dual Scale in Mils & Microns
  • 0 - 1 Mil (0 - 25 Microns)
  • 0 - 2 Mils (0 - 50 Microns)
  • 0 - 4 Mils (0 - 100 Microns)
  • 2 - 12 Mils (50 - 300 Microns)

Features

top

The Gardco IC gauge is in the form of a stainless steel wheel approximately 2" in diameter made up of 3 disk sections approximately 5/8" thick. Machined from a single piece of stainless steel stock, the two outer disks are of the same diameter. The center disk is somewhat smaller and is eccentric to the outer disks.

When the gauge is rolled over a wet film the eccentric disk will pick up the material only at and below the actual thickness which permits its immediate and direct reading. The mil scale is engraved on one side of the gauge, and the micron scale on the other side.

Directions for Use

top
In Use

Clasp the gauge with the thumb and forefinger so that the gauge body is free to turn. Place the 0 - 1 mil range gauge on a freshly coated surface at the 1.0 mil (25 micron) graduation mark and roll the gauge one-half a revolution to the "0" mark. Lift the gauge and place on another part of the surface with the 1.0 mil mark in contact with the coating.

Then roll the gauge in the opposite direction to the "0" mark. Examination of the center disk will show thickness at which pickup of the wet coating thickness has taken place and the averaging of these values may be the true wet coating thickness.

IC Thickness Gaugeis rolled over the film and the wet film thickness is read directly on either side of the gauge. Resolution of 0.05 mils (1.0 microns).

 

General Information

top
Whenever, wherever and however coatings are applied, the thickness of application is of paramount importance. If the film is too thin, the hiding power will be poor, and the substrate will show through. In addition, there will be a reduction in the protective capabilities of the coating. If the coating is too thick, not only may there be a loss in intended physical properties, but there will be a reduction in coverage and a proportional increase in cost. The use of the Gardco IC gauge will not only promote uniform application of the specified amount of coating materials, but will also insure optimum designed results from the coating used at minimum cost.

gauge Tolerance

top
Measurement and support surfaces of the Gardco IC gauge are over six inches in length. The gauge range is within half of this length and each half contains 20 graduation marks on the 0 - 1 mil scale and 25 graduations on the 0 - 25 micron scale. Due to inherent geometries for highest accuracy measurements the gauge should not be used between the first and last two graduation marks of the gauge range. Between these units the graduation marks are within the tolerance of the table shown below.

 

Certification

top
All Gardco IC gauges are produced and checked in such a manner to qualify under MIL STD 45662A for certification traceable to the National Institute of Standards and Technology. This certificate at an additional cost meets the requirements of ISO 9002. The tolerance of a particular gauge will be so certified at gauge midpoint and near its lower and upper recommended use limits and a suitable certified will be included with the shipment of the gauge.

Optioanl Handle for the Model IC gauge

top
IC Gauge Handle
Handle Diagram

A brand NEW ergonomic gauge handle is now available for use with the Gardco IC gauge with the exception of the skinny type. It offers a very comfortable precision grip handle that can be quickly and firmly attached to or removed from the gauge. It is useful as an aid in aligning the gauge on the test surface.

When the gauge is used on a moving surface, the handle aids the user to keep his hand at a distance from such surface. It also may prevent the possibility of dropping the precision instrument onto a costly rotating roller.

The handle is about six inches long and is produced from solid bar stock aluminum. The handle axle is designed to accept all Gardco produced Model IC & Model C gauges.

The gauge is held in place on the handle with one of the gauge grips so it is readily removable for cleaning or reassembling for use of the gauge with grips only.
