    Card size thickness, 6 mm only, for convenience of carrying.●The results of polarity judgment are indicated by both light and sound or may be indicated by sound only. N Pole (red LED): Sound in short intervals. S Pole (blue LED): Sound in long intervals●Since this checker detects a magnetic flux density of 1 mT (10 G) or over, it can be used for checkinga demagnetized state in a simplifi ed manner.※For precise measurement of the magnetic fl ux density, please use the Tesla Meter.

  • Ultrasonic Leak Detector

    VPE - Superior Signal Company

    The Patented Superior AccuTrak VPE represents state-of-the-art technology for pinpointing leaks is air conditioning and refrigeration systems. AccuTrak is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called "heterodyning" it translates the sound to a lower frequency which your ear can interpret. AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. AccuTrak is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.

  • Residual Intensity Calibrator

    CAL291 - Larson Davis, Inc.

    Under IEC and ANSI standards, a sound intensity measuring system consists of a two microphone sound intensity probe and a dual channel processor. The accuracy of the intensity measurement is strongly dependent upon the phase accuracy between the two measurement channels, including the microphones. Sound intensity measurement systems are classified into Class 1 or 2 based upon the pressure-residual-intensity index which is measured using a residual intensity testing device. For direct calibration or verification of the accuracy of a sound intensity measurement system, IEC 1043 and ANSI S1.9 call for the use of a sound intensity calibrator which delivers to the probe microphones the simulated intensity at a specified temperature, atmospheric pressure and nominal microphone separation.

  • Studio Microphone

    SM4000 - BSWA Technology Co., Ltd.

    SM4000 series phantom powered studio microphones are for precision recording and measurement of sound with NO color added. They can be used to record essentially any instrument for a truly accurate representation of the original sound.

  • Stethoscopes

    SKF Condition Monitoring Center

    Excellent sound quality helps to reliably identify the possible cause of the noise

  • Testing & Measuring Meters

    Bionic Scientific Technologies

    Coming with sturdy construction, user-friendly features and high quality sound and noise measurement.

  • Decoders

    LokSound - Electronic Solutions ULM GmbH & Co. KG

    With the LokSound family decoders we offer all model railroaders who want the utmost of authenticity on their layout, a real highlight. With LokSound , the excellent features of ESU-decoders are even more enhanced by the addition of sound functions. Its sounds simple, but “wow”: In the future, your locos not only run like the prototype, they sound exactly like it! That’s made possible through our award-winning LokSound technology- the reference for good sound on the layout since its introduction in 1999. By the inventor. By ESU. LokSound decoders are available for various applications, depending on gauge or digital system.

  • DC Measurements


    Standard Windows sound cards do not respond to DC or frequencies lower than a few Hz. (See Why Sound Cards Block DC Signals below for explanation.)There are two general approaches to get true DC response from a standard sound card: Modify the card, or add an external circuit to convert the DC into an AC signal which can be easily measured by an unmodified card.

  • Daqarta v5.10 Data AcQuisition And Real-Time Analysis


    New Fcal option allows any Windows sound card to measure DC values like temperature or pressure using simple external circuits you can build yourself. Or, measure MHz frequencies with a simple prescaler. DAQARTA v5.10 turns your Windows sound card into a precision laboratory instrument, loaded with advanced features. Put your sound card to work!

  • Sebalog N-3 network

    N-3 - SebaKMT

    In a Sebalgo N-3 network you always have daily measurement data for Vergfgung. Time-consuming shutdown of the individual logger is not necessary thanks to the automated Dagtenbertragung. Sign Logger leakage, you can query the automatically recorded Geuschdaten of the measurement points concerned. The sound data are transmitted automatically and are available depending on the configuration on the same day. But that''s not enough, you can sound data logger together several correlate to learn exactly where the sound source is. Through an automated daily synchronization of the entire logger network will ensure that the correlations of the highest accuracy are.

  • Acoustic Test Chambers


    Small Device Test Chambers are used for >Basic sound level measurement of small products and equipment >Pre-compliance testing of small products and equipment >End of line manufacturing test on small products and equipment Small Device Test Chambers provide acoustic isolation from outside sounds and/or reduce the sounds from the device under test radiating into the host

  • Animal Ultrasonic Vocalization Measurement Chamber

    SmartChamber - Metris B.V.

    SmartChamber is the latest product in the Metris portfolio and provides the ideal environment for high quality Ultrasonic Vocalization measurements. In addition it is an answer to the growing requests for a measurement environment in which external stimuli and crosstalk between measurement cages is minimized. Current Sound Attenuation Chambers or Cubicles are designed to provide some sound isolation against normal laboratory sounds. For several reasons these chambers are not very suited for ultrasound vocalization experiments:

  • USB-GPIB Bus Connector

    FX-910 - Qualectron Systems Corp.

    Scan Time: 100 µs~500 s (depending on Computer Memory). Bandwidth: 10 Hz - 96 kHz (depending on Sound Card). Maximum Allowable Input Voltage (if connected directly): about 2 VAC (depending on Sound Card). Selectable sampling frequency (up to 192 kHz), sampling bit resolution (8, 16 or 24 bits) and sampling channels (one or two) (all depending on Sound Card) 

  • Test Chambers

    Anechoic - ViAcoustics

    Free Field Test Chamber for sound pressure level measurement, sound power level determination, acoustic research and audio measurement applications

  • CAD Tool

    Sabin - Acoustic Engineering

    Sabin is a powerful CAD tool for room acoustics engineers. Based on statistical calculations, it determines the acoustical parameters of a user defined room, such as the reverberation time T60, the sound pressure level, and the RASTI as a measure of speech intelligibility. These parameters are updated dynamically, while the user is changing simulated sound sources and absorbing materials.
