Mechanical Dry Film Thickness Gauge 233
·Film measurement is an important method for using and testing pain and coating. Dry film is a determinate factor on judging appearance, protective performance and persistence.
·Thin dry film can not provide enough protection but reduce the covering properties. So it must assure the consistency of these values by executing with the minimum thickness according to Technical Specification.
·On the other hand, over painting will lead to a thick coating and in consequence the cost increases. Moreover, a thick coating doesn’t always mean a good performance. It might be a negative effect at drying time.
·Physical and mechanical performance of the coating is determined by thickness of dry film. Executing a meaningful test needs a well-proportioned dry film. Wet film thickness gauge is available to test paint which just brushed and calculate the thickness value of dry film. If there is different between measurement and indicated value, it needs to be corrected immediately. Dry film thickness gauge is used for measuring thickness of final coating.
·Portable and easy operation is good for nontechnical people. Firm structure, clear reading data.
·Test can run at any surface. The whole mechanical design is applicable to glass, wood, metal and plastic material.
·Compare to other thickness gauge, mechanical one offers a more competitive price.
Application:
·For any surface
Measurement Principle
·Altitude difference between coating surface and exposed material (D) is measured by the pin (1) on the meter. Two supporting feet (2) should be put on the coating surface (3).
· Design and Function
·Meter is enclosed in a chromeplated metal case. Supporting feet stretch from the bottom with the contact pin in protective sleeve. The groove near the sleeve is for adjusting the pin through the flat of a glass plate. The spare part is in the scope of supply. The gauge with attachments is in a box.
Measurement Process:
·Configuration
·Take off the protection cap and put the gauge straight on the glass plate. If it doesn’t indicate as zero, manually adjust it to zero by the groove.
·Prepare measure point
·The coating needs to cut a 3mm zone with caution until the material is reached at measure point.
Measurement
·Put the gauge on the measure zone and touch the exposed material with contact pin, dry film thickness can be read directly. (Unit: μm) Put a razor under the feet when measuring soft coating.

Mechanical thickness gauge has a series of advantages
·It is portable, easy to operate and can also be used by non-technical personnel. The structure is firm and the reading is clear at a glance.
·The measurement can be made on any surface. Because it is all mechanical, it can be applied to glass, wood, metal or plastic substrates.
·Compared with other types of thickness gauge, mechanical thickness gauge has better price.
Test principle
The height difference (d) between the upper surface of the coating and the exposed substrate area is measured by the pin · moving freely under the dial, and two feet · are placed on the coating surface.
Design and function
The dial instrument is enclosed in a chrome plated metal case. The supporting foot extends from the bottom of the instrument, and the pin is provided with a protective sleeve. The slot on one side of the protective sleeve is used to adjust the pin, which is adjusted through the plane of a glass plate. This accessory is included in the scope of supply. The dial with accessories is packed in a box.
Measurement procedure
·Setting: remove the protective cover and place the instrument vertically on the plane of the glass plate. If the pointer reading is not zero, it can be adjusted through the slot in the protective cover until the pointer reaches zero.
·Preparation of measuring point: at the measuring point, the coating shall be carefully scraped off a 3mm area until it reaches the substrate.
Place the measuring instrument on the measuring area so that the pin contacts the bare substrate, and the dry film thickness can be directly read out, unit: μ m 。 If it is a soft coating, put a razor under the support.
