Cirrus Optimus Yellow Sound Level Meters
The Optimus Yellow sound level meters are a range of state of the art sound level meters that have been designed to meet the very latest standards for noise measurement instruments and provide the highest level of performance possible while being simple to setup, use and operate.
Applications
- Simple noise level testing
- Noise ordinance enforcement
- Community noise assessment
- Fire & emergency alarm testing
- Machinery servicing and maintenance
There are many noise measurement applications where integrated noise levels, such a Leq and Lavg are not required and where basic noise data such as Sound Level (SPL) or Maximum Sound Level (Lmax) are all that is needed. These applications include simple noise level testing, noise ordinance enforcement and testing of fire and emergency alarms. The Optimus Yellow instruments are ideal for these applications and can be upgraded to add further functions.
Features
- Simple operation
- Simultaneous measurement of all parameters
- High resolution color OLED display
- Latest digital technology
- Ergonomically designed case
- 120 dB measurement range
- Optional data logging with VoiceTag audio recording
The Optimus Yellow will measure every parameter simultaneously so there is no possibility of you setting the wrong function, but only the most important data is displayed on the screen. Where data logging is fitted, store this information for download to the NoiseTools software.
The B Versions of the Optimus Yellow provide data logging of over 10,000 records as well as allowing VoiceTage audio information to be sorted before each measurement. These recordings can be played back in the NoiseTools software to provide notes and documentation for each measurement.
