一级及二级声级计及数据记录仪

The CR:800B is an Integrating Sound Level Meter with all of the measurements required by the Noise at Work Regulations, as well as for general noise assessments and surveys. The CR:800B can also be used with an outdoor measurement kit for Environmental noise measurements. As with all Cirrus Research Sound Level Meters, a Measurement Kit is recommended which contains all of the accessories needed to use the instrument.

In addition to the Broadbａnd measurement provided by the basic instrument, the CR:800B can be upgraded to incorporate 1:1 and 1:3 Octave Bａnd filters, allowing the CR:800B to be used in a wider range of noise measurement and control applications. The menu-driven operation allows quick access to the commonly used functions, while allowing more complex operations to be used when required.
