Phynix Pocket Surfix® X

Portable coating thickness gauge

The Pocket-Surfix® X-Series coating thickness gauges are portable gauges enabling quick, reliable and precise coating thickness measurement of varnish, paints and electroplated coatings on iron/steel or non-ferrous metals.

The coating thickness gauges are particularly handy thanks to an integrated probe. The measuring probe has a highly wear-resistant measuring tip made of carbide metal and thus guarantees a very long lifetime. A plastic foot with large footprint and V-groove ensures vertical positioning on level, cylindrical and curved surfaces.

The bright LED backlight enables easy reading of measured values even under difficult conditions. All Pocket-Surfix® X-Series devices have a data memory and can be connected to a PC via a USB 2.0 connection.

Three versions are available:

  • Pocket-Surfix® X-FN: for measurements on iron/steel and non-ferrous metals
  • Pocket-Surfix® X-F: for measurements on iron/steel
  • Pocket-Surfix® X-N: for measurements on non-ferrous metals
