The Casella Cel CEL-240 is a 30dB to 130dB digital sound level meter. It is designed using the latest digital technology with 2-key operations. This device can easily specify the frequency wEighting and time wEighting. In addition to that, the meter allows simultaneous display of instantaneous and maximum sound pressure level measurement. It has a high-resolution LCD that displays a bar graph or graphical time-history of noise levels and offers an easy assessment of current noise environment. The CEL-240 automatically recognises the application of a calibrator and with a single keypress adjusts the calibration. AC output provided for DAT tape / PC wav file recording or headphone applications. This device comes with 3AA alkaline batteries, windshield, and a carry strap.
