Bedrock Elite - Model i9 -Acoustic Measuring Device
The Bedrock i9 is a versatile and precise class 1/type 1 acoustic measuring device engineered for a wide range of applications. It is equipped with a premium 1/2-inch prepolarized microphone capsule, making it an ideal choice for accurate acoustic measurements. Complying with IEC 61672 standards for sound level meters, the Bedrock i9 offers additional functionality beyond basic measurement capabilities. It shares its core platform with the Bedrock i5, but it has been specifically developed to meet class 1 specifications. The i9’s microphone capsule is detachable and compatible with many popular high-end UNC capsule types from various manufacturers. It includes necessary accessories such as a ruggedized waterproof carrying case, a quickstart guide, a microphone calibration certificate, a USB cable, and a foam windscreen. With a focus on precision and efficiency, the Bedrock i9 is an attractive option for consultants and acousticians looking for an affordable yet high-performance measuring solution.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.
