25DL PLUS
 The Panametrics-NDT™ Model 25DL PLUS 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 and sizes. A large Liquid Crystal Display displays both
the live ultrasound waveform and the thickness reading. Operation of this
handheld gage is intuitive with a color-coded keypad and direct-access number
keys.
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 our
full line of contact, delay line, and immersion transducers to solve an almost
infinite number of measurement problems.
Internal
datalogger
The 25DL's internal datalogger stores, recalls, and
transmits 1,750 waveforms and more than 18,000 thickness readings along with
alphanumeric Identification codes.
Waveform
display
The A-scan shows both the live waveform and the thickness
reading, which is ideal for turbine blade inspections and any other application
where the user needs to ensure proper transducer alignment.

TECHNICAL Specifications
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. |
Thickness Measurement
Range:
Steel: 0.006 - 20" (0.15 - 500 mm)
Plastic: 0.003 -
2"(0.08 - 50 mm)
Thickness range depends on material, transducer,
surface condition and setup selected, extended thickness ranges are possible
using custom setups.
Material Velocity Range:
0.02000 - 0.55110 inch/ µS
(0.5080 - 13.9979 mm/ µS)

Measurement Rate: 4, 8, 12, 16,
or 20 measurements per second Transducer Frequency Range: 2.25 - 30 MHz
Three Differential Modes: Standard and Percent:
Thickness difference and percent difference between actual measurement and
reference value. Rate Reduction: Display actual thickness and percent difference
from setpoint. Both values can stored in the internal datalogger.
Min/Max Mode: Works in conjunction with FAST Mode for
rapid location of minimum or maximum thickness reading and associated waveform.
Two Alarm Modes:
1) Standard Hi-Low
2) Previous
thickness (Absolute or Percentage). Both with audible and visual indicators
Application Auto-Recall: Automatically adjusts internal
parameters and zero offset for a wide variety of transducers. Stores 25 standard
transducer setups and up to 35 custom transducer setups
