  • Riverboat SP

    Teledyne Marine RD Instruments

    The Riverboat SP is the top choice for deployment of the Teledyne RDI StreamPro acoustic Doppler current profiler. Upgrade from the standard StreamPro float to the more stable, rugged and fully corrosion-resistant tethered boat. The Riverboat SP makes safe, easy measurements of discharge in relatively slow and fast flowing waters. Made of unbreakable polyethylene, the Riverboat SP is strong and can handle tough deployment conditions. The standard boat configuration fits a TRDI StreamPro ADCP, and the latest instrument clamp is suitable for the StreamPro with or without an internal compass upgrade.

  • High Speed Riverboat

    Teledyne Marine RD Instruments

    ​For the best data quality in the most challenging measurement conditions, the High-Speed Riverboat is the new benchmark for acoustic Doppler current profiling for discharge measurements. The advanced hull design allows the boat to slice through standing waves and still maintain instrument position and data collection. Fast flowing water, sometimes problematic with conventional tethered boat designs, can be handled with relative ease with the High-Speed Riverboat. Made of high impact UV resistant ABS, the High-Speed Riverboat is strong and robust to cope with the worst deployment conditions.​

  • Particle Sizing Device

    PA Fast Sizer 100 - Partikel-Analytik-Messgeräte GmbH

    PA Fast Sizer 100 is a powerful, reliable and easy to use particle sizing device which delivers reliable and reproducible results in concentrated, turbid, colored or viscous dispersions. Invasive sample preparation procedures are not necessary. The device features non-invasive and non-destructive acoustic technology which is based on the viscous effect observed in dispersions. The resolution depends on the density difference between particles and solvent and on the volume concentration of the particles. The contributions of dust and other impurities can be neglected in most of the cases. Thus, field samples can be measured with ease.

  • Partial Discharge Testing Equipment

    3i - Scope T&M Pvt, Ltd.

    The portable multipurpose 3i device (Intellectual Insulation Indicator) is for eff ective high-voltage equipment insulation monitoring on-line. The 3i device measures and analyses partial discharges (PD). For eff ective PD measurement and noise rejection, there are two types of sensors used in the device: the acoustic sensor and the TEV sensor. Both the sensors are built into the device case, and so do not need any connection cables. The device is supplied in a strong metal case; at the faceplate there are the colored screen and two buttons: power button and function button.

  • Headphone Test Fixture

    AECM206 - Audio Precision, Inc.

    IEC 60318-4-compliant accessory simplifies earbud and headphone measurement in lab and production environments. The AECM206 Headphone Test Fixture is a dense, robust fixture mounted on a resilient base to isolate ambient noise, which can adversely affect measurement integrity. Equally capable in both R&D and production test applications, it is well-suited for testing circum-aural, supra-aural and intra-concha headphones and earbuds. The AECM206’s high level of acoustic isolation also enables the measurement of noise-reduction performance of ANC (active noise canceling) headphones, as well as the evaluation of hearing protection ear muffs.

  • Material Compatibility Test System (MCTS)

    MB Dynamics Inc.

    Automotive squeaks occur when materials in contact rub against one another causing annoying noises from friction-induced stick-slips. Automotive itches are a special category of squeaks that can develop when rubber or plastic rubs against glass or paint. The MB Dynamics Material Compatibility Squeak & Itch Test System (MCTS) is designed and manufactured to subject contacting pairs of materials and actual vehicle parts to precisely controlled interference & motion under in-vehicle environmental conditions in order to acquire, monitor, analyze and report friction and acoustic characteristics with the objective to:

  • Voice Quality Solutions

    GL Communications Inc.

    Wireless networks can impair voice, video, and data quality by various means including poor mobile phone quality, voice compression and decompression algorithms, video compression and decompression algorithms, delay, loss or gain in speech levels, noise, acoustic and landline echo, and other distortions. GL provides a compact and portable solution for Wireless Devices, and Mobile Radio testing.

  • Composite Inductors

    Pulse Electronics

    Composite inductors are constructed by inserting a pre-wound coil over pre-press magnetic core and then pressing or molding a magnetic material around this assembly.    The composite inductors are very similar to molded but typically offer lower DCR and lower overall losses.   Our composite core inductors provide a fully shielded, high energy density, soft saturation solution for applications up to 120Apk.   The construction enables the highest energy density of any available SMT inductors and also minimizes acoustic noise.   We offer both commercial grade (-40C to 125C) and automotive grade (-55C to 155) in a wide range of platforms from 4x4x2mm to 17x16x13mm.
