The Cirrus Research CR:308 basic sound level meters is Class 2 instrument suitable for routine noise level testing and basic noise at work measurements*. The data information provided by the CR:308 sound level meter is accurate and reliable, meeting international standards for Class 2 accuracy.
The CR:308 is a basic sound level meter that is perfect when you need basic noise information, capable of measuring the maximum sound level (LMax) and the sound pressure level (SPL).
The Cirrus CR:308 sound level meters provide an entry level for noise measurement across multiple sectors, and meets current international standards for noise measurement instrumentation.
Both variants provide the SPL and LMax readings, which can help you determine how loud something/somewhere is without overcomplicating the data with other acoustic information. Both variations can also measure different frequency weightings, which provides more detailed and accurate data than many other basic sound level meters on the market.
The CR:308 displays the SPL and LMax data, and comes with the ability to set your own noise level alert. Simply choose a decibel level, and when the meter records a noise level that meets or exceeds your pre-set value, a indicator will appear on the screen. This is incredibly useful when you need to know quickly and easily whether or not something is louder than a prescribed value.
