REED R7800 Coating Thickness Gauge


Automatically identifies ferrous and non-ferrous substrates

REED R7800 Offers

This coating thickness gauge is designed for non‐invasive coating thickness measurements. The R7800 features zero or two point calibration, user adjustable high/low alarms and a USB interface to further analyse results in the included software.


  • Automatically detects ferrous and non-ferrous substrates
  • Easy-to-read color LCD display
  • 360° screen rotation allows users to view measured readings from any angle
  • Durable gauge and probe construction
  • Zero and two-point calibration ensures measurement accuracy
  • Single or multi-point mode allows a user to set tolerances and quickly identify whether a coating passes or fails
  • Tri-color LEDs quickly indicate when measurements are below (red), above (yellow) or within set parameters (green)
  • Internal memory stores up to 500 groups of data
  • View stored data, charts or real-time measurement with software
  • Low battery indication and auto shut off
