MAVS-3 3 - Axis Acoustic Current Meter

by General Oceanics Inc.

The Mavs Current Meter is a true 3 axis Acoustic Current Meter which employs a differential travel time measurement technique. The current meter takes measurements across 4 acoustic axes to provide a true vector averaged velocity measurement. Programmable burst mode and triggered sampling provide the most flexible current meter available. The ...


Hadron - HE Series - Blowing Set

by Hadron Engineering Ltd.

The standard packages cover a wider array of blowers than its smaller brother the compact range. Air flows are available from 20m3/h, all the way up to 10,000m3/h at pressures up to 1 bar. The units incorporate a unique belt tensioning system, where the downward weight of the electric motor is used to apply the correct tension to the belt drives ...

Model BAS001 - Omnidirectional Sound Source

by Larson Davis, a division of PCB Piezotronics

The BAS001 Source is designed to generate omni-directional sound fields for making standard compliant measurements including: reverberation time (ISO 3382, ASTM E2235), building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-4 ISO 140-3, ASTM E336, ASTM E90, DIN 55 210). The BAS001 is typically used to saturate a room with a ...

Model BAS002 - Amplifier

by Larson Davis, a division of PCB Piezotronics

Measurement of reverberation time, sound isolation, and absorption coefficient are generally important measurements when verifying that a space or material complies with design goals. When making these measurements in the field or laboratory it is important to have equipment that is dependable, portable and easy to set up and use. When coupled ...

Model BAS003 - Directional Sound Source

by Larson Davis, a division of PCB Piezotronics

The BAS003 Source is designed to generate homogeneous sound fields using random noise in compliance with the following standards: Building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-3, ASTM E90, ISO 140-5, ASTM E966). The BAS003 is typically used to generate a noise in a free-field for the evaluation of the transmission loss ...
