| DM5E Series Wall Thickness Gauge - GE Measurement
DM5E Ultrasonic Thickness Gage
The DM5E Series Ultrasonic Wall Thickness Gage enables you to accomplish a large number of demanding tasks, especially with remaining wall thickness measurements on components subjected to corrosion and erosion. These gauges are smart, simple-to-use ultrasonic thickness gages that offer big performance in a small lightweight package. Their compact size and ergonomic shape provide comfortable one-hand use.
Features and Benefits
BENEFITS
Three levels - DM5E Basic, DM5E and DM5E DL
Thickness measurement under coating
User-friendly operator interface
New range of high performance probes
Flexible data processing
A range of measurement displays
FEATURES
Range of measurement displays:
Normal: the thickness value appears as large digits in the centre of the display
MIN Scan: a minimum thickness scan that allows the user to run the probe over the wall surface. After the evaluation period, the minimum material thickness measured is displayed
MAX Scan: a maximum thickness scan is exactly the same as a MIN Scan apart from the fact that the maximum thickness measured is displayed
DIFF/RR%: compares the measured thickness with a user-specified nominal thickness - dimensional difference between the two values is displayed, as is the percentage difference
B-Scan: displays a graphic representation of a B-Scan showing minimum thickness values - graph is derived by measuring and recording at 1 point per second
