    Thermometer has 4 unique alarms configurations: alarm triggers when temperature is higher than set point, lower than set point, outside of high or low set points or inside higher and low set points allowing precise monitoring of any appliance or experimentGreen/red lights blink and alarm sounds when out-of-range condition is detectedContinuous alarm sounds every minute for 5 seconds until the temperature returns to non-alarm condition or alarm is turned off.

  • Infrasound Measurements

    ECO-TECH

    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.

  • 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.

  • Noise Analysis Software

    noiseLAB - DELTA

    noiseLAB is a professional software recording and analysis package for making Type 1 Precision measurements to international standards. Precision Recorder: noiseLAB makes high quality recordings of up to 8 channels of sound. Precision Analysis of: Sound Level (Fast, Slow, Impulse, Taktmak. Custom Time Constant, Leq). Statistical Values (L1, L5, L10, L50, L90, L95, L99). Octave Spectra (1/1, 1/3, 1/6, 1/12, and 1/24th octave).....

  • Pattern Generator

    PSAW-121 - A Popular Science Apparatus Workshop

    The Instrument generate seven type of pattern and sound of 1 KHz. It is ideal for T.V. Testing and alignment of sync circuit and quick testing of R.F. I.F. Video and sound circuits. The equipment work on all 12 channel of T.V. It is generates pin point frequency for the desired channel. The design is as per C.C.I.R. standard.

  • Multimode Data Controller

    PK-232SC - Timewave Technology Inc.

    Timewave’s customers swear by their DSP filters and PK-232 owners love the flexibility and reliability of the most popular data controller ever built. Now with the addition of a built-in sound card, rig control, computer isolation and total USB connectivity, the PK-232SC rolls it all into one! The PK-232SC brings a new level of performance to the legendary PK-232 with sharp, accurate DSP filters for all its internal data modes and dual transformer isolation for sound card data modes.

  • 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.

  • Directional Acoustic Detector

    D.A.D. - Aqua-Tronics

    The model D.A.D. Directional Acoustic Detector features a new concept in fault locating that utilizes the speed of sound to show direction to the fault (thump) from where the operator is standing. This dual channel system is designed to work with any brand thumper. The sound of the thump is detected at different times by two microphones placed over the cable route. The DAD uses an ultra-high speed clock to determine which microphone is closer to the fault and indicate the direction the operator must go. When the operator passes the fault, the meter will indicate a reversal in direction.

  • 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.

  • Amplifier
