Class II sound level meter PCE-428-EKIT with octave filter (optional 1/3 octave filter) for frequency analysis / ICCP 40mV/PA microphone / Data logger / Weighting A, B, C, Z / Fast, slow, pulse analysis and peak analysis / MicroSD / USB cable / 3 measurement profiles / ISO calibration certificate
The PCE-428-EKIT sound level meter ensures detailed high-accuracy measurements with frequency weightings A, B, C, and Z as well as with the four sound measurement speeds Fast, Slow, Pulse, and Peak.
Additionally, the meter can store measurements in 3 different user profiles. Here the user can decide which parameters the sound level meter should record in each profile. For example, you can choose between Laeq, LcPeak, LaFmax, LaFMin and so on.
An innovative feature for the PCE-428-EKIT is the Peak function, which ensures recording of the maximum sound pressure level during a long-term measurement. A 24bit AD converter helps reduce the inherent noise to a very low level. The 48 kHz signal sampling rate allows high measurement accuracy.
PCE-4xx-EKIT
An additional kit for outdoor sound measurement PCE-4xx-EKIT can be combined with the sound level meters PCE-428, 430, or PCE-432. This kit makes it possible to measure outdoor noise with a sound level meter for a long period. The environmental noise monitoring system consists of a waterproof Peli transport case with rollers. A charger and two additional lead gel batteries have been placed in this case, which allow the sound meter to operate for up to 10 days. During outdoor sound measurement, the case can remain closed. Due to the external connections for the microphone and the power supply, all electronic components are protected from water.
The screen insulation provides protection from wind and rain, and the microphone windshield isolates the measurement from the effect of wind. The charger of the PCE-4xx-EKIT kit is waterproof and can remain outdoors. Also, a tripod is available with which the microphone can be placed outdoors.
The PCE -4xx–EKIT can be used for noise measurement in critical areas such as road surfaces in residential areas, airports, depots, as well as for measuring acoustic events.
