Optimus Green Sound Level Meters

The Optimus Green sound level meters have been created to combine the existing features from the Optimus range with the latest technological innovation and added functionality that is necessary for environmental noise to be accurately measured.  

These include:

• Real-time octave 1:3 band filters - measuring from 6.3Hz to 20kHz to accurately show variants in types of noise to help determine its source.
• Repeating measurements - allowing measurements over long periods of time.
• Audio recording during measurement - enabling the recording of the actual noise for later replay and analysis. This sophisticated feature makes it possible to track down the audio fingerprint of the noise so its source can be pin pointed.
• VoiceTag audio recording before each measurement - for note taking.

The Optimus Green is suitable for health and safety and environmental measurements. Like the other Optimus sound level meters, it can be used for basic noise and for noise at work measurements and every measurement made contains all of the available functions so there is no risk of selecting the wrong parameter or function. 

It also benefits from the ergonomically designed case, easy to use interface and 120dB dynamic range featured in the Optimus range, alongside the full free customer support service provided with every Cirrus noise measurement product. 

Dr Philip Dickinson, Professor, Sound Centre at Massey University, New Zealand, comments: “It is a first class instrument and should be the prime tool of all environmental and occupational health officers - indeed all territorial officers should have this as their first port of call for noise measurements. It has all but exceeded all my expectations and I will be recommending it to all the health professionals I meet.”
