Ultrasonic thickness gauges are the optimum tool for finding the remaining wall thickness of corroded or eroded metals such as found in steam and water piping, storage tanks, pressure vessels, etc. and where access is limited to only one side of the component. They can be used to measure most metals (forged, rolled, extruded, cast), many plastics, ceramics and glass, plus some rubber and fiberglass (depending upon composition). Some materials allow sound transmittal better than others and result in more accurate and reliable measurements. Surface condition and temperature variations will also affect thickness measurement. Dual element gauges can be employed at elevated temperatures up to +650F (+340C) when the appropriate transducer and couplants are used..

The NDT 705 is an inexpensive, easy to use thickness gauge for spot
checking corroded or eroded metals. It has been designed for the inspector who
occasionally needs an accurate instrumentand is not built to take the daily wear and tear
of the full-time NDE technician. Principle - Ultrasonic Pulse-echo with dual element transducer  Measurement Range - 0.04 to 20.00 inches (1.0 to 500mm) in steel depending on transducer, material and surface condition Transducer - Standard ¼ dia. x 5 MHz with 3 foot long integral cable Others available for special applications Calibration - Single point automatic calibration Can also calibrate to a know material velocity Frequency - Selectable 2 or 5 MHz Automatic V-Path Correction Selectable inch or metric units of display Resolution - From 0.04 to 4.00” = 0.001” More than 4.00” = 0.01” 1 to 100mm = 0.025mm More than 100mm = 0.1mm Gain - Adjustable for different transducers Alarm - Programmable lower limit activated luminous LED Display - 0.56” high 4 digit LCD with switchable backlight Keypad - Sealed, dustproof and watertight membrane keypad Automatic Turn OFF after 3 minutes of no use or manually by keypad Powered by two 1.5V size AA alkaline batteries  Operating Time - Up to 100 hours using alkaline batteries without backlight High impact molded ABS plastic housing Size - 5”H x 2.8”W x 1.4” (125 x 70 x 35mm) Weight - 12 oz. including batteries Standard Kit Includes the Gauge with alkaline batteries, 1/4" element diameter 5.0 MHz Transducer with integral cable, 4 oz. bottle of ultrasonic gel Couplant, Operation Manual, Quick Guide Card and foam-lined aluminum Carry Case Click for NDT-705 .pdf document Back to Top The NDT 710 is a small hand held thickness gauge that is very easy to use for spot measurements of corroded or eroded metals, plastics and many other materials. Gauge memory retains last calibration and measurement reading even after the unit has been turned off. Sound Velocity Range: 0.0197 to 0.3930 in/ms (500 to 10,000 m/s) Size: 1.4" H. x 3.1" W. x 5.7" L (35mm x 79mm x 145mm) Temperature Range: + 10 to 120 F (-10 to 50 C) High impact molded ABS plastic housing Weight: 11 oz. with batteries (309 grams) Powered by a single 9 volt alkaline battery. Click for NDT-710 .pdf document The NDT 715 offers the same specifications as our field proven 710  gauge. It is a small, hand held thickness gauge, only 2.5"W x
4.75"H x 1.25"D and weighing only 10 oz. It is designed to make reliable
spot check measurements an has a SCAN MODE that will capture and display the thinnest
measurement taken during a strip scan along a length of material. Housed in a
extruded, anodized aluminum housing with nickel plated aluminum end caps and a weather
resistant keypad the gauge is a bit more rugged than the 710 making it suitable for your
toughest working condition. The 715 is also more resistant to potential interference
from RFI fields than the 710.

Ultrasonic Pulse-echo with dual element transducer
MMX-6 A dual element gauge with both pulse-echo and multi-echo
SPECIFICATIONS MMX-7 A dual element multi-echo (thru paint) gauge with large digit numeric and
B-Scan displays and Data Logger
CMX A versatile ultrasonic thickness gauge that combines the ability to
measure wall thickness with or without coatings and simultaneously measure the coating
itself. Time-based B-scan and large data storage capacity compliment the advanced
features of this brand-new gauge. Available in three models. Standard (CMX),
with data logging (CMXDL) and with data lgging, A and B-Scan display and three independent
gates (CMXDL+) |
Pulse-echo Mode for flaw and pit measurement and Multi-Mode
(Echo-Echo mode) to measure through and eliminate paint and coatings. Built-in
automatic gain control.
The POCKETMIKE ™
A general purpose thickness gauge that combines the instrument and transducer into a single package allowing true one hand operation. The PocketMIKE is only 1.38" diameter x 4" long and is packaged in a machined stainless steel housing environmentally sealed to IP67. The 4-button operation, Automatic On-Block Probe Zero and Automatic Gain Control provides a very capable yet very easy to use instrument.
