The CHECK•LINE

TI-25LT Ultrasonic Thickness Gauge accurately mea-

sures the thickness of steel. This gauge uses the “pulse-echo” principle of
ultrasonic testing where a short ultrasonic signal is transmitted from the
probe. The signal travels through the measurement sample until it is reflect-
ed back towards the probe from the back side of the material. The elapsed
time for the complete cycle is measured and converted to an accurate
thickness reading.

The TI-25LT can be used to measure the extent of corrosion on the opposite,
inaccessible side of the wall by using the “Subtractive Method.” When the
thickness of the original wall is known, subtracting the thickness reading
obtained from the TI-25LT will determine the extent of corrosion at the
point of probe placement. If the original wall thickness is not known, test
readings should be made along a grid of equally-spaced points to obtain a
profile of the thickness readings. The smallest thickness reading will locate
the area of greatest concern.

The TI-25LT is factory-set to measure steel. As a “no cost” option, the
TI-25LT can be factory set to measure on any other single material instead
of steel. However, it can never be used for more than one material. If this
capability is required, contact Electromatic to purchase the TI-25M upgrade
explained below.

Easy upgrade to full TI-25M functionality (contact Electromatic for
details). The 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.

RECAU T I ON S

Do not use the standard probe in applications where material temperatures
exceed 200 °F (100 °C) as the probe will be damaged. Special High
Temperature Probes should be used. Consult factory.

Keep the gauge free of dust (especially metal powders, carbon, etc.) as they
will damage the gauge. Use a damp cloth to clean the gauge after use.
DO NOT USE CHECMICAL SOLVENTS OF ANY KIND.
