SV 307A

SV 307A for continuous noise level monitoring through the integration of a class 1 sound level meter with a 4G modem and GPS. The waterproof casing can be removed to gain access to the user interface with color screen and operating keyboard. The SV 307A is equipped with a patented MEMS microphone with guaranteed lifetime and measurement data is stored on a removable microSD card and sent via an integrated 4G modem to a dedicated server in the cloud using the SvanNET platform.

This is also taken into account by system verification using an internal noise source at 90 dBA and 1 kHz, which allows you to always get information about the operating status of the microphone.

Other variables can also be integrated into the system, such as weather conditions, wind speed, wind direction, rain, humidity, etc. This includes monitoring PM2.5 or PM10 particulate material along with noise data via external sensors. The SV 307A is the ideal choice for measuring environmental noise, providing all environmental monitoring parameters for noise control, evaluation and modeling.

It is ideal for environmental measurements, construction monitoring, preparation of noise maps, industrial noise monitoring, environmental impact assessment, compliance with environmental management plans, noise control in surrounding areas, etc. and noise modeling.
