Bedrock Elite i9 Sound Level Meter
The Bedrock i9 and the tried-and-true Bedrock i5share the same primary platform. All throughout, though, the i9 has been engineered and tested to meet class 1 standards. Its detachable microphone capsule is compatible with the majority of popular high-end UNC capsule types made by different producers.
For those who demand the highest levels of precision and efficiency, the Bedrock i9 is a versatile measuring solution. This, along with its affordable price, makes the Bedrock i9 a desirable addition to any consultant’s or acoustician’s toolkit.
Applicable to a broad range of applications, the Bedrock i9 is a class 1/type 1 acoustic measuring device. This instrument is the first choice for precise and trustworthy acoustic measurements because of its premium 1/2″ prepolarized microphone capsule. While meeting class 1 requirements (IEC 61672) for sound level meters, the Bedrock i9 also provides a range of additional features.
