byko-test 4200/4500
Dry Film Thickness Gages
The byko-test 4500 film thickness gauge allows for the measurement of a variety of products. No cable exchange or calibration is needed when changing from a ferrous to a non-ferrous substrate. The large LCD display and 10 second retention of the last measured value makes the byko-test 4500 easy to use.
- Compact pocket size instrument
- One-handed design for ease of use l Integrated, non-wearing ruby probe tip
- Switchable from mils to microns
- Strong, wear resistant ruby probe tip
- V-groove in probe for positioning on cylindrical parts
- Accoustic signal for measurement confirmation
New Features
- Automatic substrate recognition
- Extended measuring range
- Faster measuring speed
- Graphic display with backlight
