Sound meters

The optimus range of sound level meters from Cirrus Research combines practicality with smart design and advanced technology.

It takes just three button presses to make a noise measurement: On, Calibrate and Start. The instrument takes all measurements simultaneously before displaying results on an OLED display. New software allows voice tags to be recorded for future reference.

To ensure measurements can be validated, instruments feature the LifeTime archive.

This stores the most important parameters into a secure section of memory which can only be downloaded using a special software program.
