Spectronics offers new diagnostic tool

The Spectroline® Marksman ultrasonic diagnostic tool from Spectronics Corp. converts and amplifies inaudible ultrasonic sound into audible sound. Service technicians using the instrument are able to hear sounds that signify problems such as electrical discharge, and seal and gasket leaks.

The Marksman MDE-1000 features a receiver, probes, and an ultrasonic emitter. A 12-inch hollow probe, when attached to the receiver, accentuates air sounds. A solid contract probe accentuates sound of wear or grinding inside gears. Standard 9-volt batteries are included for both the receiver and emitter.

Sound Metrics sonar helps manage fisheries

Sound Metrics Corp. offers DIDSON, a high-definition sonar that uses acoustic “lenses” to produce nearly video-quality images in dark, turbid waters where optical systems are ineffective.

DIDSON (dual-frequency identification sonar) can be used to estimate fish abundance, help operators understand fish behavior, differentiate between upstream and downstream movement, and assess fish habitat. It can perform activities in rivers with high turbidity and debris loads, the company said.

DIDSON can be mounted off the sides of boats, along riverbanks, and at dams. It works in shallow, rock-bottomed rivers and around structures such as dams, screens, and intakes.
