SaluTron D3 / D4 / D5 Compact Coating Thickness Gauges

SaluTron D3/D4/D5 are compact dry film thickness (DFT) gauges designed for fast, reliable coating checks on production parts.
They measure paint, plating and other protective coatings on both ferrous (Fe) and non-ferrous (NFe) substrates—supporting quality assurance and process control in powder and liquid coating lines.
Why measure coating thickness?
• Ensures consistent coating quality and compliance with specification.
• Helps monitor and stabilize your coating process (and reduce defects).
• Reduces paint consumption by preventing over-application.

  • Fast DFT measurement for both ferrous (Fe) and non-ferrous (NFe) substrates.
  • Automatic substrate recognition for correct measurement mode selection.
  • Continuous and spot measurement modes; spot mode supports averaging.
  • Compact design for easy one-hand use in production and inspection areas.
  • Model-dependent ranges (see technical specifications below).
