3000PRO Coating Thickness Gauge with Interchangeable Probes

Click images to enlarge.
The new Check-Line 3000PRO Series coating thickness gauge is a multifunctional fully menu driven gauge for fast, professional and precise coating thickness measurement for:
  • paint and electroplated coatings on iron and steel
  • paint and anodizing coatings on non-ferrous metals and on austenitic stainless steels
The user will select one or more probes best suited for their application to connect to the 3000PRO gauge as all the probes are interchangeable and their internal calibration is stored within a small microchip inside the probe connector housing. This provides for quick and easy hot-swapping from one probe to any other in seconds.

Eight (6) separate probes are offered for a wide variety of applications.


  • Automatic identification of the substrate
  • Highly wear-resistant measuring poles made of carbide metal
  • Special probes for unusual measurement tasks
  • Safe use even for special applications such as sand-blasted surfaces, small parts and curved surfaces
  • Scan mode for the quick recognition of coating thickness variations on large surfaces, including display of minimum and maximum readings
  • Display backlight for poor ambient lighting conditions
  • Online statistics with all statistical parameters
  • Extensive memory storage for recording of up to 10,000 data pints in up to 500 separate files "batches"
  • Alphanumerical file names can be used to identify each of the separate files "batches"
  • Infrared interface for wireless data transfer to printer and PC or via built-in RS-232
  • Includes FREE software for transferring data to a PC including histogram function
  • Optional high temperature footer for measuring on surfaces up to 150 °C/302 °F
  • Includes Traceable Calibration Certificate
  • 1 Year Warranty
