3 Models
- Measures Coatings on Ferrous (steel, iron) Only
DCN-3000FX - Measures Coatings on Non-Ferrous (non-magnetic metal) Only
DCFN-3000FX - Combination Model, Measures Coatings on both Ferrous and Non-Ferrous metal

The Check-Line 3000FX Series coating thickness gauge is a powerful and precise coating thickness gauge designed for measurement of paint and non-magnetic coatings on steel and iron as well as paint and anodizing coatings on non-ferrous metals. All external probes are machined to ultra-high standards and utilize a unique, hard-metal probe tip which prevents probe wear.

A v-notched footer provides a stable footing on small cylindrical parts, which can be removed to expose a "micro-probe" sensor perfect to measure on small surfaces and parts.

Where to use 3000FX Series?
Wherever coatings are applied – whether on visual and aesthetic grounds, to prevent corrosion protection, or for functional and mechanical reasons – the coating thickness represents an essential quality feature. The 3000FX Series is ideal for speedy, non-destructive and exceptionally precise coating thickness measurement.


  • The 3000FX Series is a compact, lightweight coating thickness gauge for operators who require both innovative and user-friendly measuring techniques
  • The 3000FX Series ensures non-destructive coating thickness measurement on steel and non Ferrous metals
  • Data transfer to a printer or PC takes place via an infra-red interface
  • Up to 10 000 readings can be statistically evaluated: number of readings, mean value, standard deviation, minimum and maximum reading.
  • The 3000FX Series identifies the substrate and activates the appropriate measuring procedure.
  • Menu in a choice of three languages ensures ease of operation
  • The uniform contact pressure of the sensor is kept to a minimum, preventing scratches and indentations to sensitive surfaces.
  • Two optional high temperature footers for measuring on surfaces up to 150 °C/302 °F or up to 300 °C/572 °F
  • Traceable Certificate Included at no additional cost
  • 2 Year Warranty

Complete Kit

The 3000FX Series is supplied as a complete kit with gauge, ferrous and or non-ferrous zero plate(model dependent), 2 calibration standards, 2 AA batteries, hard carrying case, instruction manual and calibration certificate.
