  • Profiling CTDs

    Sea-Bird Scientific

    A CTD measures Conductivity, Temperature, and Depth. Despite the name, all CTDs actually measure pressure, which is not quite the same thing as depth. The relationship between pressure and depth is a complex one involving water density and compressibility as well as the strength of the local gravity field. The CTD data can be used to calculate salinity, density, sound velocity, and other parameters of interest. The term CTD is often used today to describe a package that includes the actual CTD as well as auxiliary sensors to measure other parameters (such as dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.) and a water sampler to collect water samples for later analysis in the lab. The term Sonde is sometimes used as an alternative to CTD.

  • 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.

  • Motor Vibrophonic Monitor

    MV-90 - ECG KOKUSAI Co., Ltd.

    A very small acoustic vibration during operation can indicate a major defect in a small-sized precision motor. The acoustic vibration is normally detected using a sounding bar applied to the ear of an inspector who judges whether to reject or pass a motor by listening to its sound during operation.This method produces different judgments according to each individual inspector, and automation is not possible. With this unit, a highly sensitive acceleration-type detector is applied to the bearing area of a motor, to directly defect the acoustic vibration.The resultant measurement is not influenced by environmental noise, and an absolute and accurate measurement can be made.

  • Turnkey Solution for Unattended Noise Monitoring

    NoiseScout - NTi Audio AG

    NoiseScout provides a comprehensive but easy-to-use 24/7 noise monitoring solution. Noise levels are recorded on-site by the XL2 Sound Level Meter and are available online for monitoring and download. NoiseScout is aimed at both short term noise assessments and long term monitoring applications. During acquisition, automated email alerts allow noise issues to be addressed before a non-compliance condition arises. NoiseScout displays the noise levels measured by the XL2 Sound Level Meter live in your web browser. The measurement data recorded out in the field is presented online in charts and dashboards. Multiple noise level meters can be monitored simultaneously within the map view, thus providing localized geographic visualization for all noise levels at a glance. Identified users can access all their projects, control their monitors or create basic view modes, allowing stakeholders to oversee their noise level data.

  • ultrasonic sensors

    Contrinex Schweiz AG

    Contrinex ultrasonic sensors provide reliable, non-contact detection of solid, liquid, granular or powdered materials in air, tolerating precipitation, humidity, dust and fumes. Target materials may be colored, transparent, polished or matt; detection is practically independent of the target's direction of travel. Diffuse-mode and reflex sensors emit bursts of high-frequency sound waves toward a target, measuring the time elapsed until an echo is received.

  • Digital Attenuators

    Telemakus LLC

    A digital attenuator is essentially the opposite of an amplifier. The attenuator reduces the power of a signal and lowers voltage while keeping its waveform. If this sounds like what you’re looking for, you have just found a quality product that will last a long time. We are available nationally to ship any of our products to you! From RF switches and USC synthesized sources to 7 bit and 8 bit digital attenuators, we got you covered!

  • Power Line Meter

    Alpha Lab, Inc.

    The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

  • Light Meter for iPhone

    Lumu Power - Lumu Labs

    Accurate exposure is essential to the nature of image making. Lumu features state-of-the-art digital light sensor for unquestionable measurements. Its advanced self-calibrated photodiode array emulates human eye response. Additional features such as IR light rejection and temperature compensation make it most advanced illuminance sensor on the market. Lumu doesn’t have battery, it gets electricity out of the sound. With its low power consumption, Lumu will require less battery as listening to the music on your headphones.
