CR:306 Sound Level Meter

 

Product Range:
CR:306

The CR:306 is a general purpose digital sound level meter which meets the full requirements of IEC 61672 to Class 2. The instrument has ‘F’ (Fast) response and both ‘A’ and ‘C’ frequency weightings. In addition facilities are provided to hold the maximum reading occurring during the measurement period.

The CR:306 allows noise levels to be checked quickly and simply, with the large display showing the Sound Level (SPL) with the standard dB(A) frequency weighting. dB(C) Frequency Weighting is also provided.

The instrument has two measurement ranges, and can measure from 35dB(A) to 130dB(A). The maximum hold function allows the unit to freeze the display showing the highest level measured. This can be used where the allowable level is given in terms of a maximum (LAFmax or LCFmax).

Key Features

Applications

The CR:306 is the ideal instrument for basic noise surveys and can be used for measurements such as vehicle noise checks, workplace spot checks, fire alarms and audible warning systems as well as the installation of sound systems.
There are also many applications where a Sound Level Meter can be useful but where a high specification instrument would be too costly. In these situations, the CR:306 becomes a simple low cost addition for service engineers.

Ordering Information
The CR:306 Sound Level Meter is supplied as standard with a 24 month warranty, operating manual, a certificate of calibration, battery, calibration screwdriver and a windshield.
