Noise-measurement equipment manufacturer Cirrus Research has launched the Optimus Green sound-level meter. Designed for environmental, occupational, and industrial hygiene noise, Optimus Green has been created to combine the existing features of the Optimus range with the latest technological innovation and functionality that, according to Cirrus, is necessary for environmental noise to be measured accurately.

Features include: real-time octave 1:3 band filters; a capability for measurements to be made over a long period of time; audio recording during measurements – making it possible to track down the audio fingerprint of the noise so its source can be pin-pointed; and VoiceTag audio recording before each measurement, for note-taking purposes.

The Optimus Green also benefits from an ergonomically-designed case, easy-to-use interface, and 120dB dynamic range, says Cirrus. Visit the company’s website, www.cirrusresearch.co.uk for more details.
