    Description

    Welcome
    at company auctions
    PatKor Shop
    In this auction we offer:
    We offer a digital sound analyzer type 2238.
    The device is designed for comprehensive sound measurements in terms of intensity, characteristics of the total noise intensity per unit time and other parameters.
    Thanks to the microprocessor signal processing, the device enables a range of measurements that were previously only possible with the use of complete measuring sets of considerable weight and dimensions.
    The device is adapted to work with a PC and thanks to the software, it ensures the creation of comprehensive libraries of sound parameters and the recording of signals on an ongoing basis over a long period of time.
    This is especially important when we want to make accredited measurements needed for all kinds of noise opinions, e.g. for compensation or scientific research.
    The offered analyzer has the option of automatic calibration using the 4231 type calibrator, which is included in the auctioned set, which makes the calibration process simpler and cheaper. The calibrator included in the set is universal and is also suitable for the calibration of other devices measuring sound intensity.
