Olympus Introduces Handheld Ultrasonic Thickness Gage for Internally Corroded Pipes and Structures
Posted:
Olympus is pleased to announce the release of the 27MG Ultrasonic Thickness
Gage that is designed to make accurate measurements from one side on
internally corroded or eroded metal pipes or walls. It weighs only 12 oz. (340 g)
and is ergonomically designed for easy, one-hand operation. Despite its compact
size, the 27MG has many innovative measurement features utilizing the same
technologies that are available on more advanced thickness gages. The durable,
rugged 27MG is battery-operated and features a large, backlit LCD with easy-to-
read numerals, and an intuitive color-coded keypad with direct access to many
key features.

Standard features include Automatic Probe Recognition to ensure optimal
transducer performance, Auto Zero compensation to enhance the accuracy of
measurements on hot surfaces, Gain Adjust to improve measurements on
sound-attenuating materials such as cast metals, Differential mode, Hi-Low
Alarm settings, and a Min/Max mode that recalls the minimum or maximum
thickness at 20 measurements per second.

The 27MG comes standard with the low-cost D7910 dual element transducer
that enables inspectors to make thickness measurement for many basic
corrosion applications. For measurements on very thin or thick materials, or
small diameter pipes, Olympus has available a full line of dual element
transducers. Olympus transducers compatible with the 27MG feature Automatic
Probe Recognition that optimizes transducer performance by automatically
recalling the default V-path correction.

The 27MG is designed for inspectors and maintenance engineers that need to
monitor the wall thickness in metal pipes, tanks, beams, and structural supports
that are susceptible to corrosion on the inside surface. An ultrasonic thickness
gage provides a quick, cost-effective solution by transmitting sound into the
material from the outside, making it unnecessary to damage the part.
