Thin Film Handy Holiday Detector M/1 - Tinker & Rasor

Thin Film Handy Holiday Detector M1

Greatly Improved, Fast, Accurate & Economical

The Tinker & Rasor Model M/1 Detector has received wide acceptance in the corrosion control and industrial painting industry as a device for locating bare spots or (holidays) in the thin protective films which are sprayed or brushed on metal or concrete surfaces. This detector is non-destructive and the applied voltage to the coating never exceeds 67.5 volts at any time.

The inspection electrode consists of a 2" x 2" x 7" cellulose sponge which, when dampened with water, is moved over the coated surface. When the electrode passes a void or bare spot, a small current flows and actuates an audible signal in the instrument. The damp sponge provides an electrically conductive film that contacts the surface being inspected and insures good inspection even in corners and around irregular shapes where holidays are most likely to occur.
