The Extech 407790 Real Time Octave Band Analyzer is an auto ranging Type 2 integrating sound level meter featuring 1/1 and 1/3 Octave Band real-time noise analyses. The 407790 offers five measurement parameters: SPL (Sound Pressure Level), Leq (Equivalent Continuous Sound Pressure Level), LE (Sound Exposure Level), Lmax (Maximum Sound Pressure Level), and Lmin (Minimum Sound Pressure Level). The built-in memory stores 12280 data records in sound level mode and 1024 records in Octave mode. The stored data can be easily transferred to a PC with the supplied software and RS-232 cable. This meter permits choice of ‘A’, ‘C’, or ‘Flat’ weighting and ‘Slow’ / ‘Fast’ response times. AC and DC analog output signals are available for chart recorders and other external recording devices. Careful use of this device will provide years of reliable service.
