The optimus yellow instruments 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 whilst being simple to setup, use and operate.
Applications
- Simple Noise Level Testing
- Noise Ordinance Enforcement
- Community Noise Assessment
- Fire & Emergency Alarm Testing
- Machinery Servicing & Maintenance
There are many noise measurement applications where integrated noise levels, such as Leq or 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, future proofing your investment.
Simple operation to make measurements simple
The instruments will measure every parameter simultaneously so there is no possibility of you setting the wrong function, butt only the most important data is displayed on the screen. Where data logging is fitted, store this information for download to the NoiseTools software.
Key Features
- Simple operation
- Simultaneous measurement of all parameters
- High resolution colour OLED display
- Latest digital technology
- Ergonomically designed case
- 120dB Measurement range
- Optional Data Logging with VoiceTag audio recording
Data Logging of measured data
The CR:152B and CR:151B instruments provide data logging of over 10,000 records as well as allowing VoiceTag audio information to be stored before each measurement.
These recordings can be played back in the NoiseTools software to provide notes and documentation for each measurement.
A clear upgrade path to protect your investment
A sound level meter should be an investment and the optimus range has been designed with the future in mind.
The units can be upgraded and enhanced as and when new regulations are introduced or when new functions are available.
