High Precision TG4100B Digital Ultrasonic Thickness Gauge 128X64 Pixel LCD With Backlight

TG4100B Ultrasonic Thickness Gauge

Usage
Widely used to measure the thickness of metal materials. Especially display its advantage for measuring the thin piece and high precision measuring. What’s more, it can also through the thin coating layer and paint layer, and also be used to measure ultra thin wall with paint layer like fire extinguisher.

Pipe Walls Measurement

The thickness of a pipe can be measured accurately with this gauge. The measurement range is shown in the following table:

PT-06 ≥φ30 ≥ 0.8

PT-04 ≥φ20 ≥ 0.8

The split-plane of the probe may be along the pipe axis or perpendicular to it as shown in the following figures:

                                                       Pipe samples

In this case, the readings on the screen will change with some regular patterns and the smallest display value should be taken as the thickness value.

For small pipes, measurement should be made in both directions (moving probe a little bit). For large pipes, measure the thickness of the wall along the direction perpendicular to the pipe axis. See the following figure:
