optimus range of sound level meters

The Optimus range of sound level meters uses the latest display technology and digital signal processing (DSP) techniques to provide you with a very powerful yet easy to use meter. The ease of use comes from the fact that all parameters are automatically measured at the same time, so no need to think about what you need in the split second before starting the measurement.

Making Noise Measurements

Making measurements usually consists of checking the calibration (adjustments are automatic), recording a voice tag if required*, and then taking the readings.

If the data logging option is fitted then all the measurement parameters are stored, along with time, date and other relevant information.

Future Upgrade

Not sure if you need data logging? Maybe you don't know at this stage whether you might need an Integrating sound level meter. It could even be that eventually you may need octave band filters.

All of these features can be added at a later date. Some can even be fitted without returning the meter to the factory by remote update.

We can even change the meter from Class 2 to Class 1, although of course it must be returned for this upgrade.
