  • Loudspeaker / Audio Transducer Tester

    NWin - NaTCH Engineering

    NWin is a software package designed specifically for production testing loudspeakers and other audio transducers. It can make sophisticated pass or fail decisions and report on production performance. The user creates the tests they need and then combines them to create a test sequence. You will need a PC fitted with a sound card, a microphone (possibly with a pre-amp), a power amp if you're doing this seriously, and a loudspeaker ... to test.

    IMV Corporation

    A compact Signal Amplifier to make optimal signal processing being connected with the Servo type Accelerometers. It is used for Vibration Acceleration Measurement, Waveform Observation, for various Analysis in combination with the AC Voltage Meter, Oscilloscope, FFT Analyzer respectively. Furthermore, Voltage signals from the Microphones or Sound Level Meters can be output to the instruments like Recorders along with the Vibration Signals.

  • Low Noise Converter for Radio Amateurs

    Kuhne electronic GmbH

    The concept of software defined radios (SDR's) is becoming increasing popular in both commercial, military and Amateur Radio circles. In their basic form, the use simple front end filtering followed by a Quadrature Sampling Detector (QSD) with the post detection processing done in software using the sound card found in PC's. Several popular kits have been developed to introduce Amateurs to the concept.

    * 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.

  • LPT port 4 bit diagnostic card for Desk pc and notebook

    ST8669 - Shenzhen Sintech Electronic, Inc.

    1. It is fit for both laptop and desktop with the parallel port (LPT) to which POST codes is output.USB provide power.2. The value of four-bit-code PC Analyzer's "initiative code" is specified and it is "0000" or "FFFF"."initiative code" is clear at a glance. While the value of conventional two-bit-code PC Analyzer's "initiative code" is uncertain and man is unable to distinguish accurately by unaided eye.3. Court defects by difference sounds coding with build-in speaker。

  • CORRELATORS

    C-3 - SebaKMT

    The Correlux C-3 correlator locates leaks in drinking water pipes. Pressurized water at the leak location creates a noise which travels out in all directions of the pipe.This noise is recorded, amplified and sent wirelessly to the correlator by two sensors (piezo microphone, hydrophone) which are attached to the pipe (e.g. valve, hydrants).The Correlux C-3 compares both signals (correlation) and calculates the exact distance to the leakage on the basis of the delay time of the signals, the sensor distance and the sound velocity in the pipe.

  • Class 1 Measuring Instrument

    Bedrock SM90 - Bedrock Audio

    The Bedrock SM90 is a versatile class 1/ type 1 acoustic measuring instrument, suitable for a wide variety of applications. With its high-quality 1/2" prepolarized microphone capsule, it is the instrument of choice whenever accurate and reliable acoustic measurements are required. The Bedrock SM90 conforms with class 1 requirements as a Sound Level Meter (IEC 616272), but also offers a variety of other functions:

  • Compact Audio Generator

    72-490 - Tenma

    Highly versatile audio generator is perfect for sound system and speaker component testing. Its high precision and remote VCO input make it suitable for the serious test environment, yet its compact size and low cost make it suitable for any tool box. Features: •Rotary frequency adjustment •Independent sine and square wave outputs, each with their own level control •VCO input for remote frequency setting •1/4" unbalanced outputs •Selectable 0dB/10dB output attenuator

  • Blanket Testing Equipment

    Automatic Testing rubber blanketsUp to 40,000V AC, 100,000V DC or both Allows Testing to ASTM D1048 and F479 StandardsThe TSM Series is The VON Corporation’s fully automated blanket test solution. Units allow testing of all standard rubber blankets, even class IV. Tests are timed and an audible alarm sounds failures or test complete, with bright flashing colored lights signaling which position failed or test complete. Four and Eight position models are available.

  • HF Analyzer

    HFA-3 - ROM-Elektronik GmbH

    PC connection precision measurements using the latest microprocessor technology Long-term recording simplest operation Measurement display in W / m or mV / m Frequency filter for major mobile phone networks and other services (GSM900, GSM1800, UMTS, DECT, WiFi, Bluetooth) precision EMC -LogPer antenna sound latest circuit technology best quality supported by universities confirmed by reports

  • Hi Pot Meters

    Bierer & Associates, Inc

    The HI Pot Device is designed to Hi Pot de-energized 15kV class cables. The tool transforms 18 Volts from the battery to approximately 8,000 volts DC. When the battery is installed and the safety switch is in the closed down position, the unit is in voltage detection mode. The unit should be in this position when installing the device, as it will sound a warning alarm if you approach an energized source. When the safety switch is lifted and the toggle switch is switched up, the unit is in the Hi-Pot mode and the high voltage DC is being applied.

  • Dynamic Signal Analyzer & Data Acquistion

    Electroacoustics Toolbox - Faber Acoustical, LLC

    Electroacoustics Toolbox is a modularized, multi-channel dynamic signal analyzer and data acquisition platform for Mac. It brings powerful new tools to the Macintosh platform for multi-channel, audio-band data acquisition and real-time analysis of electrical, acoustical, and electroacoustic signals and systems. It enables precise measurements of acoustic quantities, such as equivalent and time-weighted sound levels, as well as acoustic and electroacoustic systems, such as listening rooms and loudspeakers.

  • Echo Sounder

    SonarMite - Ohmex Ltd.

    The SonarMite is the smallest, lightest, truly portable hydrographic echo sounder system available. • Transducer Frequency 235KHz Active Transducer • Beam Spread +/- 4 Degrees minimum • Depth Range 0.30m to 75.00m (Software limited). • Accuracy +/-0.025m (RMS) • Sound Velocity Range 1400 to 1600 m/sec • Data Output Range 2Hz • Ultrasonic Ping Rate 3 to 6 Hz (Depth dependent ).

  • Digital Ultrasonic Maintenance System

    VPE-2000 - Superior Signal Company

    The Superior AccuTrak VPE-2000 is the first digitally controlled ultrasonic detector. Like two instruments in one it uses two independent sensors supported by separate electronic circuits configured specifically to their own sensor. This assures optimum sound clarity and frequency response. When switching between the airborne and contact sensors all settings are retained in memory! Digital LED meters let you establish baselines, perform trending, and accurately repeat these tests better than older more expensive analog instruments.
