Measuring Range in Steel 0.040 - 6.00 inches 1.00 - 150.0 mm The TI-25LT Ultrasonic Thickness Gauge accurately measures wall thickness and the extent of corrosion - from only one side! Standard configuration: In its standard configuration, the TI-25LT Wall Thickness Gauge is factory set to MEASURE STEEL ONLY Optional configuration: As a “no cost” option, the TI-25LT Wall Thickness Gauge can be factory set to measure on stainless steel. Easy upgrade to full TI-25M Ultrasonic Thickness Gauge functionality (refer to separate data sheet). TI-25M Ultrasonic Thickness Gauges measure 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 Ultrasonic Thickness Gauges require factory installation of enhanced circuit board, new firmware andkeypad.
