For occupational noise, Optimus Red is the ideal instrument.

Simple to use with the very highest level of performance, you can be sure that an Optimus Red will give you what you need.

With three simple button pushes (On, Calibration, Start) you can start a measurement and get all of the information you need to assess and deal with your noise issues.

All of the 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 have set the instrument to display the Leq and you need to see the Octave Bands, just press the right arrow key once and you will see the octave band. Press again to see Dose view which will give you all of the information you need to meet OSHA, MSHA or ACGIH.
