Optimus Sound Level Meter

Applications that demand high accuracy, but do not need an Integrating meter (see below): basic surveys, alarm testing, ordinance enforcement.

Occupational noise surveys. For basic surveys, the CR162A is ideal. If you want to download to a computer then the CR162B has this fitted. For more advanced assessments and hearing protector calculations, the CR162C it ideal.

The Optimus Sound Level Meter has a very modular design, so you can add features such as data logging and octave band filters at a later date, usually without even having to return the meter. Software and firmware (the software in the meter itself) can all be upgraded remotely.

Before starting a measurement the meter asks if you want to record a Voice Tag. At this stage you can speak into the microphone and record up to 30 seconds of notes. You can even record the noise itself for your records. When the measurement is downloaded to a computer the voice tag automatically comes with it. You can listen to it on the computer's speakers. Included with all Data Logging versions of the meter.

The data logging meter stores parameters such as the Leq and Peak at a rate of between 10ms and 2 Seconds (user programmable). When downloaded, this gives a detailed graph of the noise over time.

Data logging meters store the octave band spectrum every second or every 1/2 second, giving a very detailed analysis of the noise over time.

Many measurement standards and regulations state that you should check a meter's calibration before starting. To calibrate the Optimus Sound level Meter, just fit the Calibrator, switch it on and press the Calibrate button.
