PRECISION THICKNESS GAGES

NONDESTRUCTIVE TESTING

GE Panametrics

The Model 25 ultrasonic precision
thickness gage provides cost-effective
solutions in applications where the
opposite side of the test material is dif­ficult or impossible to reach. An
important benefit of this handheld
unit is its ability to make thickness
measurements on many materials in a
wide variety of shapes, sizes, and
geometries. A 5-digit LCD with back­light provides easy viewing of thickness
measurements. Operation of this
handheld gage is intuitive with a color­coded keypad. The Model 25 offers
measurement features typically found
in more complicated and expensive
units but at a lesser cost.

One of the many unique features of
this gage, Application Auto-Recall,
allows the user to select and recall any
of the stored standard or custom
transducer setups in the gage’s
memory. This permits easy switching
among GE Panametrics’ full line of
contact, delay line, and immersion
transducers to solve an almost infinite
number of measurement problems.

MEASUREMENTS

Mode 1: Time interval between excita­tion pulse and first backwall echo.
Using contact transducers

Mode 2: Time interval between the
first interface echo after the excitation
pulse and the first backwall echo.
Using delay line or immersion
transducers

Mode 3: Time interval between succes­sive backwall echoes following the first
interface echo after the excitation
pulse. Using delay line and immersion
transducers
