  • Non-Contact Voltage Testers

    PeakTech Prüf- und Messtechnik GmbH

    User-friendly tester for non-contact voltage testing from 50 V to 1000 V AC. Suitable for outlets, lamp sockets or against wire insulation testing. If AC voltage is present at the relevant measuring point, this is indicated visually by a flashing red LED and the integrated buzzer sounds. If the measuring point is voltage-free, the test probe lights up permanently green.

  • Remote End Cable Testers

    XLR Sniffer/Sender - Sound Tools

    Designed by Rat Sound to deal with the "real world" of pro audio, the SoundTools Sniffer/Senders are the perfect tools for live environments. Test snake lines and cables when the ends are at a distance and avoid running extra cables just to test. Utilizing phantom power the Sniffer end can quickly test snake lines in minutes. The aluminum barrels eliminates the problem many testers face with solder joints failures and the unit will never rust. 3 simple LED’s will instantly diagnosis your cable as it tests for every possible shot, open, or cross wire in XLR cables. If the LED’s read all green you cable will work!

  • Suspension Component Test Systems

    MB Dynamics Inc.

    Acoustic quality, vehicle dynamics and stability, and driver comfort play an increasingly important role in the development of new chassis and suspension systems – both passive and active. Noises in suspension components can cause customer dissatisfaction and lead to high warranty costs and are difficult to diagnose especially on historically-used, noisy hydraulic test rigs. The MB Suspension Component Test Rig (SCTR) enables dynamic simulation of real road excitations and synthesized waveforms, performing industry-standard Force-Velocity and Force-Displacement tests and low speed friction tests, and assessing other NVH and structure-borne noises for comprehensive performance characterization and sound and vibration analyses on a wide variety of chassis components.

  • Low-Noise Design

    Nelson Acoustics

    * Sound Quality: Find our what your end users like or dislike about emitted noise. * Low-Noise Product Design: Apply interinsically-quiet design principles to your device * Fan Noise: move cooling air quietly * Gas Flows: Reduce noise from industrial gas processes * Advanced analysis and signal processing: Finding the relevant "needle" in the "haystack" of data.

  • Distribution Modules

    MDM - Meyer Sound Laboratories Inc.

    MDM products offer convenient power distribution and flexible routing of audio, AC power, and RMS to Meyer Sound loudspeaker systems. The MDM-5000 is a rack-mount unit for quick connection and efficient distribution of AC power, audio signals, and RMS to LEO Family systems. Standard multicore connectors for audio and power are on the front panel, with discrete connectors on the rear for audio, RMS, and power.

  • Optical Inspection Tool

    Optopig - Norsk Elektro Optikk

    Optopig is an optical inspection tool, mainly for inspection of natural gas pipelines. The optopig tool gives both images and 3D information of the pipe and the inner pipe surface i.e., you can both measure the depth of a cavity as well as see how it looks. The interpretation of the findings will therefore be easier than interpretation of data from traditional MFL and ultra sound testing devices.

  • Acoustic Probe

    AA-Ultrasonic - IPEC Ltd.

    The AA-Ultrasonic acoustic probe is designed for use on air insulated terminations where a clear sound path between the electrically stressed insulation and the probe is present. The sensor is extremely sensitive and can detect activity below 10pC. The probe has a magnetic base to allow coupling to steel enclosures and a swivel head as so the detecting sensor can be aimed directly at the HV point. Corona in air and surface tracking can seriously damage high voltage insulating surfaces in a way that will ultimately lead to flashover and complete failure of the insulator. This discharge activity creates acoustic emission that can be detected using a high frequency sensor. The magnitude of the acoustic emission is indicative of the degree and severity of the discharge activity.

  • Vibration Testing

    Response Dynamics Vibration Engineering, Inc.

    We most often characterize a problem first and work from known conditions, and stay in “the known” as we proceed by making sense of what we observe as we move forward. We test and analyze the change in dynamics we are trying to create in real-time, on site, and often make changes to our experimental test plan on the fly as we discover how a system is actually behaving. In doing so we often get meaningful results from which we can make sound engineering decisions in a short time frame. We don't just make measurements and spit out data. We help identify the problem and propose solutions.
