The Elcometer 304 ultrasonic material thickness gauge is ideal for measuring the material thickness or material sound velocity of virtually any material such as metals, plastics, glass, epoxies & ceramics in a wide range of applications.


Key Features Explained:

  • Measures uncoated & coated surfaces

Flexible & easy to use, the Elcometer 304 doesn’t just measure uncoated surfaces but can also measure coated surfaces. Using Echo Echo ThruPaint™ mode (EE), coatings up to 2mm (80mils) are ignored.


  • Choose & customise the reading display

The Elcometer 304 has a choice of display modes allowing the user to select the most appropriate for their needs; Readings, Selected Statistics, Bar Graph, Run Chart & Differential Mode.


  • User definable limits for pass/fail indication

Limits can be set on the Elcometer 304 for individual readings or for each batch with audible & visual pass/fail warnings.


  • Store each measurement for further analysis

Up to 100,000 readings can be saved into the gauge memory as each measurement is taken, which can be downloaded later into an inspection application or into ElcoMaster® for further analysis and reporting.


  • Data output to PC, Android™ or iOS† mobile device

Connect the Elcometer 304 via Bluetooth® or USB to a PC, Android™ or iOS† mobile device & download the data into an inspection application or into ElcoMaster® for instant report generation.
