IEC 61672 Class 1 sound level meter and IEC 60651, IEC 60804.
SLM supports measurements in either air or water and can be combined with all other physical measurement parameters, vehicle bus systems, video, GPS, and other math to build a thorough image of your entire measurement.
High Dynamic Range
Our top-class data acquisition hardware with 160 dB dynamic range supports all types of microphones no matter if they require 200 V external polarization or constant current (CCLD, IEPE). If the microphones have TEDS information then it will automatically be used for the measurements. The data acquisition system can be scaled for any number of microphones, which can be effortlessly calibrated with a calibrator.
Advanced Math - All at the Same Time
Predefined standard frequency weighting A, B, C, D, and Z), time weighting (Fast, Slow, or Impulse), sound pressure level, equivalent, peak, minimum & maximum sound pressure levels, sound energy, impulsivity of sound, statistical noise level (LAF1, 5, 10, 50, 90, 95 and 99 % classes of values) are all available at the same time.
Flexible displays offering digital meters, analog bars, time-domain recorders, narrowband FFT, and octave analyzers can be freely combined to show your SLM data in real-time as well as in post-processing.
