Battery powered M/1 wet sponge holiday detector

AC powered M1/AC wet sponge holiday detector

 
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.

The design of the M/1 includes a regulated inspection voltage, instant calibration verification, and a six-cell battery pack using commonly available "AA" size batteries. The unit is housed in a tough ABS plastic instrument case. For high-noise environments, Tinker & Rasor offers comfortable headphones as an option for the new M/1.

Model M1/AC has the same specifications as Model M/1, with the exception that it is powered by 110V AC power, as opposed to battery power.
