Extech 407790-NIST Real Time Octave Band Analyzer with NIST certificate

This auto ranging Type 2 integrating sound level meter features 1/1 and 1/3 Octave Band real-time noise analysis. 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 12,280 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.

Applications:

• Real time analysis of noise from any source such as machinery or vehicles
• Monitor office or plant noise and store data for later reference and analysis
• Maintain noise level statistics for internal and external audits
• Perform machinery noise monitoring or use for noise reduction programs
