The FN CM gauge features a cabled probe for reaching into narrow or confined spaces where a gauge with an integrated probe cannot fit. It also possesses the highest rated accuracy, and the highest precision readout of our gauge models (to 0.1µm). Gauge functions are accessed through a user-friendly scrollable menu system.

It has a rich feature set and an adjustable brightness multi-colour LED display that is easily readable even in dimly lit conditions. It includes features from our FN Evo coating thickness gauge, having both a memory and statistical functions. It is high spec and quick and easy to use – simply hold the sensor against the surface to be measured and the coating thickness is automatically displayed on the large colour LED screen.

In addition, the CM offers a selectable continous reading setting where the probe can be held and moved along a surface. This is in addition to the normal single reading setting where the probe is placed on the surface and removed to take one reading at a time.

The gauge also automatically calculates and displays statistics of minimum, maximum, average, and standard deviation of the thicknesses read.

  • High accuracy – the highest rated accuracy and resolution of our coating thickness gauge models
  • Cabled probe – allows reach into narrow and intricate areas to take measurements
  • Reads coatings on thin substrates – Underlying metal thickness of 0.4mm and upwards
  • Continuous reading setting – selectable on/off to allow probe to be held and moved along a surface without lifting
  • Auto measure – simply place the probe on the surface to be measured
  • Auto detection and display of substrate type (Fe/non-Fe)
  • Integrated dual sensors – enables reading on ferrous and non-ferrous substrates with automatic deteiont, no probe switching, and no user intervention
  • Adjustable brightness large colour LCD display – for clear, error free readings even in dimly lit environments
  • 50 place memory – automatically stores most recent measurements
  • Statistics calcuation – automatic display and calculation of average, minimum, maximum, and standard deviation
  • Scrollable menu system – for intuitive operation
  • V-notched probe – eases reading on curved surfaces
  • Plastic probe surround – assists in protecting surfaces from damage
  • Metric and Imperial units supported (µm/mil)
