Elcometer 307 Ultrasonic Precision Thickness Gauge

The new Elcometer 307 ultrasonic precision thickness gauge is designed to provide accurate measurements of thin materials.

Measures thin materials with pinpoint accuracy

The new flexible, easy to use Elcometer 307 has a measurement range of 0.15mm (0.006”) to 25.40mm (1.000”) with ±1% accuracy, across three measurement modes; Interface Echo (IE), Echo Echo (EE) & Plastic mode (PLAS).

Choose & customise the reading display

The new Elcometer 307 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 307 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 307 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.

Transducers

 

Intelligent Single Element Transducers

 

When selecting a transducer it is important to choose one which will meet the specific application’s needs. The type of material to be tested, the measurement range, the shape of the substrate (curved or flat) and the size of the material should be considered when selecting the appropriate transducer. All part numbers starting with ‘TXC’ are Microdot Right Angle transducers and are supplied with a calibration certificate.
