  • Fast

Measuring over 60 readings per minute in standard mode and over 140 readings per minute in scan mode, the Elcometer 500 coating thickness gauge can signicantly reduce your inspection times.

  • Reliable

The Elcometer 500 will only display the coating thickness reading if the signal strength indicator turns green, preventing false or incorrect readings. If the coating thickness is outside the measurement range, the Elcometer 500

tells you on the display.

  • Intelligent

The Elcometer 500 measurement probes are supplied with user replaceable probe tips. If the tip is damaged or wears during use you can replace it and carry on. The gauge even informs you when you need to change the probe tip, maximising inspection time.

  • Easy to Use

There is no need to set up gates, range values or know the thickness of the coating, simply select the coating material from the gauge library and start measuring.

  • Ergonomic

The Elcometer 500 gauge and intelligent probes have all been ergonomically designed for continuous use. No force is required to take a reading.

  • Rugged

Robust, ergonomic and sealed against dirt and water, equivalent to a rating of IP54, the Elcometer 500 has been designed to work in harsh environments, making it the ideal gauge for the laboratory or the job site. Coating Thickness Gauge Elcometer 500

  • Powerful

The Elcometer 500 wirelessly transmits readings, statistics and batches via Bluetooth® or via USB straight into your inspection application or into Elcometer ’s Mobile App ElcoMaster®, for instant report generation either at your desk or in the field, uaing your mobile.

1. Coating Material Library
The Elcometer 500’s advanced measurement technology means that you no longer need to know how thick the coating should be or to set up measurement gates before taking a reading. Simply switch on the gauge, select the coating from the calibration library and take a reading - it is that easy.

2. Material Thickness Calibration
To obtain the greatest measurement accuracy, the Elcometer 500 can be calibrated using the known thickness of the coating to be measured. If a sample of known thickness is not available, the Elcometer 500 Coating Calibration Mould (CCM) can be used to create a coating of known thickness which is traceable to both National and International Standards.     

3. Sound Velocity Calibration
The Elcometer 500 can be calibrated by entering the speed of sound from the Product Datasheet available from the coating manufacturer.
