Do you need to measure occupational noise?
For occupational noise and industrial hygiene applications, the optimus red is the ideal instrument.
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 Fast Sound Level and you find that you need Slow, just change the time weighting and you can see the information you need.
