Frequency analysis is available in the A Version (1:1 Octaves) and the B Version (1:1 & 1:3 Octaves) along with Audio Recording during measurements and VoiceTag™ for note taking.

Quick, simple and easy to use

With just three button pushes you can start a measurement and get all of the information you need to assess and deal with your noise issues.

Your investment is protected as we’ve designed all of the optimus instruments to be upgradable with new and additional measurement functions.

Record a VoiceTag™ before each measure to store your notes and comments directly into the noise meter. When you download the measurements to the NoiseTools software, click on the icon to replay and listen to your notes.

Audio Recording during Environmental Noise measurements

A feature unique to the optimus green sound level meters is the Audio Recording during measurements. You can record the actual noise during a measurement by either pressing the Audio Start/Stop buttons or by using the triggering functions.

What ever you need, it’s already measured.

All of optimus sound level meters will measure all of the available functions at the same time. This means that no matter what the display is showing, you can be sure that you can’t choose the wrong function.

For example, if you’ve set the instrument to display the Leq and you need to see the 1:3 Octave Bands, just press the right arrow key twice and you’ll see the 1:3 octave bands. Press again to see the Dose view which will give you all of the information you need to meet OSHA, MSHA or ACGIH.
