Elcometer 550 Non-Contact Powder Thickness Gauge - Discontinued


Discontinued Product – for servicing use only

Using third generation proven airborne ultrasonic technology, the new Elcometer 550 Powder Thickness Gauge accurately predicts cured coating thickness by non-contact measurement of coating powders.

  • Accurately predicts the cured coating thickness within ± 5% of the reading or ±5µm (±0.25mils)
  • Ergonomic gun designed for comfort when taking multiple readings
  • Hand-held probe allows easy positioning of the sensor for fast measurement
  • Large illuminated colour display with positioning graph to guide orientation of sensor probe
  • Tough aluminium case, ideal for testing in an industrial environment

By carefully controlling the thickness of powder applied to a product, you can minimise your powder usage and ensure the quality of your coating. As contact measurement solutions damage the finish and do not predict the cured coating thickness, measuring the powder thickness pre-cure requires a non-contact solution.

Easy to Use

  • Easy to read, large colour display
  • Adjustable screen brightness for all test conditions
  • Ergonomic probe - ideal for continuous testing
  • Can be used straight out of the box with minimal setup time
  • On-screen guidance graph and handle LEDs help you orientate the probe sensor for fast, accurate measurements


  • Fast, accurate and repeatable results
  • Can be used in accordance with ASTM D7378-Procedure C
  • Proven, third generation, airborne ultrasonic technology
  • User-programmable set up to account for varying powder shrinkage rates

Enhanced Technology

  • Measure thicknesses from 30 - 110μm (1.18 - 4.4mils)
  • 1mm² (0.04 sq in) measurement area - ideal for flat, curved and small surfaces
  • Test coatings on a wide range of substrates, including metal, wood, MDF, plastic and pre-coated surfaces
  • Laser targeting to accurately position the gauge at the correct distance from the surface to be measured
