CEL-430 Integrating Sound Level Meter with Memory from Casella USA
|
|
Introduction
The CEL-430 integrating sound level meter is a new design that encompasses many of the benefits of the existing CEL-450 and CEL-490 products in a simple and easy to use meter. All DSP technology ensures that the whole of the audio range of noise levels are covered by a single dynamic span. This eliminates the need to change ranges during a measurement and ensures that all the noise captured faithfully and included in the overall result. All the most popular noise units are simultaneously calculated during the measurement and can be read off the large display or recorded for later download to the optional software package.

PC Software
The CEL-430.A meters are available with the optional dB30 dedicated Windows package download and control software. Record the measurements as normal and they will be stored in the meter's memory for later transfer to the computer for printing. The dB30 software also allows the meter to be reconfigured, labeled and stored to suit new measurement requirements. These user defined setups will be ready to go when the meter is next used. A real time output is available for viewing the noise readings on a PC.
