Low Cost,
Ultrasonic Wall Thickness Gauge
TI-25LT
Measuring Range
0.040 - 6.00 inches
1.00 - 150.0 mm
 |
The new CHECK-LINE TI-25LT Wall Thickness Gauge accurately measures wall
thickness and the extent-- from only one side!
Standard configuration: In its
standard configuration, the TI-25LT is factory set to measure steel
only.
Optional configuration: As a "no
cost" option, the TI-25LT can be factory set to measure on any other
single material instead of steel.
Easy upgrade to full TI-25M
functionality (refer to separate data sheet). TI-25M measures on all
metals, ceramics, glass and most rigid plastics. It provides Single
Reading and Scan modes, where the probe is dragged over a large
measuring area. The minimum reading recorded during the "scan" is
displayed.

Upgrade to TI-25M requires factory
installation of enhanced circuit board, new firmware and keypad.
