Description

CEL-430-A2-K1 Integrating Sound Level Meter Standard Kit by Casella

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 is 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.

Key Benefits

Single 120 dB dynamic range covers all noise levels
Simple easy-to-use operation
Pre-configured setups for the most popular measurements
Available with ANSI/IEC type 1 and type 2 accuracy
Automatic recognition of calibrator when applied to microphone
Large custom LCD with automatic backlight
Memory for result storage
Pc software program for archiving and printing results
Meter can be remotely configured for special measurements from dB30 PC software
Fixed microphone and preamplifier for simplicity

Applications

Short term hand held measurements
workplace noise assessments
community noise measurements
noise nuisance monitoring
vehicle noise certification
simple survey meter for front line measurements
noise mapping around machines in the workplace
product noise testing
compliance measurements to local noise ordinances
real time output to personal computer

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 the computer.
