  • Mini Carbon Monoxide Gas Detector

    Model - KM CO-910 - KUSAM-MECO

    KM-CO-910 Carbon Monoxide meter detects the presence of Carbon Monoxide (CO) & measures concentrations between 1-1000 parts per million(PPM). The meter indicates the presence of CO by a reading on the LCD & a beeper tone. The beeper function much like clicking of a geiger counter: above 200PPM, the beeper sounds continuously with the concentration of CO; from 35PPM to 200PPM, the beeper sounds discontinuously with the concentration of CO.

  • Infrasound Measurements


    Is sound that is lower in frequency than 20 Hz (hertz) or cycles per second, the "normal" limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher intensities it is possible to feel infrasound vibrations in various parts of the body.

  • Humidifier Vibrators

    Fuji Ceramics Corporation

    Ultrasonic energy generated from the piezoelectric elements will be larger. The center of the sound pressure is focused with certain directivity. The Power of the focused sound pressure, it lifts up the water surface, and arises the water column. Water film of water column tip is tearing, and then splashing the misty of fine particles to the air. This action is the atomization principle by ultrasonic. In the high-frequency and high-power, and it provides a dedicated vibrators having excellent durability.

  • Real-Time Spectrogram

    (RTS) 4.0 - Engineering Design

    Real-Time Spectrogram (RTS) 4.0 provides viewing, measurement, and editing of unlimited-length sound files. RTS 4.0 operates as a module within SIGNAL 4.0, so measurement data can be stored in the SIGNAL logfile and sound segments can be exported directly to SIGNAL buffers (as well as saved to disk). Analog I/O is provided by one of the direct-to-disk analog I/O programs described below.

  • Ultrasound Measurements


    Is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws.

  • True Dual-Channel Analysis on iOS

    IOScope - Faber Acoustical, LLC

    With IOScope, measure loudspeaker impedance, frequency response, and sensitivity. Measure a room impulse response. Tune a large sound reinforcement system, time-align a set of surround sound speakers, or optimize your home stereo. Determine the actual cutoff frequencies of your latest speaker crossover circuit, or teach your students the fundamentals of Fourier analysis of dynamic systems.

  • Carbon Monoxide (CO) Meters

    Extech Instruments Corporation

    An audible indicator increases in tone starting at 35 ppm. The higher the concentration of co, the faster the alarm will sound. Above 200 ppm, the alarm will sound continuously. A backlight on the display can be used for low light areas. Additional features include: max hold, data hold, and auto-power-off. The meter comes complete with a 9-volt battery, protective holster, and case.

  • Personal Safety Voltage Detector

  • Ultrasonic Leak Detector

    ULD-420 - Amprobe Test Tools

    When equipment begins to fail due to an air or gas leak or vibration, or electrical discharge, the leakage point emits an ultrasonic sound wave that is above the natural range of human hearing. The ULD-420 Ultrasonic Leak Detector converts this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure. When working in unpressurized systems or the pressure is not sufficient enough to detect or verify a leak with the Receiver alone use the Transmitter.

  • Electronic diagnostic stethoscope

    DS-3 - DeltaTech Electronics

    Electronic automotive diagnostic stethoscope DS-3 is used to listen to acoustic effects of working parts of vehicles and machines. It is equipped with signal level indicator, allowing to quickly estimate the amplitude of vibrations in a 10 point scale. Fully digital signal processing allows for clean and undistorted sound in the headphones. Stethoscope offers selectable digital filter cutting out frequencies above one of 10 pre-defined values that can improve hearing sounds overpowered by high-frequency noise and vibrations.

  • Analog Ultrasonic Inspection System

    ULTRAPROBE 100 - UE Systems Inc.

    The Ultraprobe senses high frequency sounds produced by operating equipment, leaks and electrical discharges. It electronically translates these signals by heterodyning them down into the audible range so that a user can hear these sounds through a headset and see them as intensity increments on the meter. Heterodyning works the same as a radio in that it accurately transforms the sounds so that they are easily recognized and understood.
