The top-of-the-range Optimus+ Green has been specifically designed as an environmental noise meter and is perfect for measuring and monitoring exposure to noise pollution and environmental noise sources, including construction sites, windfarms and industrial operations.

Available as either a Class 2 or Class 1 sound level meter, built to IEC 61672, the Optimus+ Green environmental noise meter provides everything you need to measure both occupational and environmental noise, to the fullest extent. Capturing the full range of sound parameters simultaneously, there’s no other noise measuring instrument you need to measure and monitor exposure to environmental noise.
