Description
Elcometer 304 Ultrasonic Material Thickness Gauge
The new 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.
Measures uncoated & coated surfaces
The new flexible, easy to use 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 new 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 new 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 later be downloaded into an inspection application or into ElcoMaster® for further analysis and reporting.
Data output to PC, Android™ or iOS mobile device
Connect the new 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.
Key features of the Elcometer 304 Ultrasonic Material Thickness Gauge include:
- 2-Point, 1-Point, Material, Velocity, Thickness Set & Factory calibration options, allowing accurate measurements of a wide range of materials
- Up to 3 programmable calibration memories, allows the user to select a saved calibration method without the need to recalibrate the gauge
- Hi & Lo limit indicators provides indication of problem areas
- Selectable measurement rate of 4, 8, 16Hz (4, 8, 16 readings per second)
- Scan mode at 16Hz, ideal for measuring a large surface area
- Integrated zero disc, ensures maximum accuracy
- Stores up to 100,000 readings in up to 1,000 sequential batches for further analysis & downloading to a PC or mobile device
- USB & Bluetooth® data output to ElcoMaster® PC or ElcoMaster® Mobile App for instant report generation
