The DFT-400 Dry Film Thickness Gauge provides a fast and economical solution to non-destructive dry film thickness assessment on ferrous substrates only. The DFT-420 Dry Film Thickness Gauge provides a fast and economical solution to non-destructive dry film thickness assessment on ferrous and non-ferrous substrates. In order for coating systems to perform as designed the thickness of each coat of paint must be within tolerances set by the material manufacturer – assessing the dry film thickness of the paint  after the coating process is an invaluable tool to ensuring that the thickness of the coating is as specified. The DFT-400 & DFT-420 Dry Film Thickness Gauges are ergonomic and light weight yet tough and reliable, and are powered by standard alkaline batteries. Both units are switched on by placing the probe on the substrate to be measured and feature single button operation and intuitive menus. An audible signal confirms that a reading has been successfully taken and the back lit screen displays readings clearly and quickly. Each gauge is supplied with calibrated for life; this means that there is no requirement to calibrate the gauge before use, or in changing climatic conditions - simply use the zero plate provided to zero the gauge before use, or in changing climatic conditions, to ensure the accuracy of the readings. Both gauges are available in integral or separate probe design both with an industry leading polished ruby tip ensuring millions of fast, reliable and accurate readings of up to Fe 5000 microns or/and NFe 3000 microns. Each gauge features a sleep mode which turns the unit off after a short period of inactivity, by placing the probe onto a surface to be measured the unit reactivates and is immediately ready for use. The DFT-400 & DFT-420 are supplied in foam filled hard plastic carry cases with an additional soft plastic pouch for ease of
transportation in the job site, reference plates, 2 x 1,5 V Mignon batteries (type AA alkaline), test certificate and instruction
manual. Both gauges have hand sizes straps allowing for easy fixing on the wrist or clothes.
