#233 dry Film Thickness Gauge: complies with Rossmann, ISO 2808, ASTM D 1005, bs3900:C5 standards.

Application: on all flat surfaces

Test principle

The height difference (D) between the upper surface of the coating and the exposed substrate area is measured by means of a pin (1) with free movement on the surface and two feet (2) placed on the coating surface.

Design and Function: The dial instrument is sealed in a chromed metal case. The legs protrude from the bottom of the instrument, and the pins are protected. Slots on one side of the protective case are used to adjust the pins, which are adjusted through the flat surfaces of a glass plate. This accessory is included in the scope of delivery. The dial with accessory comes in a box.

Measurement procedure

1) Device

Remove the protective cover and place the instrument vertically on the flat surface of the glass plate. If the pointer reading is not zero, you can adjust it through the slot in the protective cover until the pointer reaches zero.

2) Measurement point preparation

At the measuring point, the coating is carefully scraped off a 3 mm area until it reaches the substrate.

3) Measurement

Place the instrument on the measurement area so that the pins touch the exposed substrate. The dry film thickness can be read directly in um.

For soft coatings, place a razor blade under the feet.
