  • Sound Level Indicators

    PCE Instruments

    A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site.An important attribute to consider when searching for a suitable sound level meter is its type or class. The type or class of a sound level meter defines the device's accuracy as per American National Standards Institute (ANSI) or International Electrotechnical Commission (IEC) guidelines. Typically, "type" is the grade according to the ANSI S1.4 standard, whereas "class" is the grade according to the IEC 61672 standard. There are two types or classes assigned to sound level meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 sound level meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.

  • SparkFun Environmental Sensor

    BME688 (Qwiic) - SparkFun Electronics

    The SparkFun BME688 Environmental Sensor is a breakout that combines a gas scanning sensor with temperature, humidity, and barometric pressure sensing for a complete environmental sensor in a single package. The gas sensor on the BME688 can detect a wide variety of volatile organic compounds (VOCs), volatile sulfur compounds (VSCs), and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. Combine that with precise temperature, humidity, and barometric pressure and the BME688 can work as a completely standalone environmental sensor all in a 1in. x 1in. breakout!

  • Spectrometers

    OCEAN FX - Ocean Optics, Inc.

    The next innovation in miniature spectrometers from Ocean Optics — Ocean FX™ — offers high-sensitivity CMOS detector performance, acquisition speed up to 3,000 scans per second, and a robust communications module that accommodates Ethernet and Wi-Fi. The new spectrometer is ideal for UV-Vis applications in food and agriculture, where acquisition speed helps with food sorting and processing; biomedical sciences, especially for absorbance measurements requiring enhanced UV sensitivity; and security and authenticity, where added communication interfaces enable simpler point-of-use instruments. Also, the onboard buffering feature ensures data integrity during kinetics measurements.
