Environmental monitoring is a crucial part of our society and is performed within many construction and infrastructure projects. Vibration, sound, air over pressure, dust, and many other parameters are monitored in construction and infrastructure projects. Blasting and drilling noise and vibrations from tunnel work is one example where noise and vibration monitoring equipment is necessary to ensure human comfort, since many people live close to construction sites in urban areas. Making sure that nearby buildings are protected and residents are comfortable is a best practice in the industry.

Robust and weather-proof design

The INFRA C50 noise monitor offers a rugged weather-proof design and is designed for a long service life in harsh conditions. Replacing and charging the batteries of the INFRA C50 sound level meter is quick and easy and is described step-by-step in the manual. See more on Sigicom Academy.

Easy-to-use system
