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.

Applications

• Short term hand held measurements
• Workplace noise assessments
• Community noise measurements
• Noise nuisances monitoring
• Vehicle noise certification
• Simple survey meter for front line measurements
• Noise mapping around machines in the workplace

• Compliance measurements to local noise ordinances
• Real time output to personal computer

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
