FLUKE DO-50537-03 Digital Sound Level Meter

The CEL-240 series is a completely new range of sound level meters that combine the power of Digital Signal Processing ( DSP) technology and simplicity and low cost of a traditional analog instrument. The meter has a low and high measurement range that covers a full 70dB on each setting and include A and C frequency scales and slow, fast and impulse time responses. A non-decaying maximum hold feature on every display captures and displays the highest sound pressure level of any noise until reset by the user. The optional software package is ideal for datalogging in spreadsheet format file for analyzing measurement data further.
