Real-Time Octave Band Analyzer

Analyze 1/1 and 1/3 octave bands simultaneously|Measures from 30 to 130 dB with ?1.5 dB accuracy Meets ANSI and IEC Type 2 standards Stores up to 12,280 data records with date-and-time stamp Connect to chart recorders and other external recording devices via analog AC/DC outputs|The Real Time Octave Band Analyzer operates as a Type 2 sound level meter with 1/1 and 1/3 Octave Band real-time noise display and analyses. It maintains noise level statistics for internal and external audits, and acquires real time analysis of noise from any source such as machinery, heavy equipment, or vehicles. A large color backlit LCD displays Leq, LE, Lmin/Lmax, Lp, L05, L10, L50, L90, and L95 readings. Choose between A, C and Z frequency weighting with slow, fast, and impulse time responses. Measurements can be initiated by one of three triggers: time, level and external. A built-in memory stores up to 12,280 data records in sound meter mode and 1,024 data points in octave mode. Stored data can be transferred to a PC via USB cable or saved on a 4GB removable microSD card to be analyzed later. Compliance: ANSI S1.4 Type 2, EN IEC 60651, EN IEC 60804, EN IEC 1260-1995
