The environmental tester is a class 2 data logging sound level meter that meets IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983 and ANSI S1.43-1997 requirements. This portable high-accuracy environmental tester has a large easy-to-read illuminated LCD screen that displays the sound pressure level (SPL) numerically and graphically in real time. The sound level data logger calculates the equivalent continuous sound level Leq (LXeq).

• Measuring range: 25 … 136 db(A)
• LXY (SPL), Leq (LXeq), LXYSD, LXSEL, LXE, LXYmax, LXYmin, LXPeak, LXN
• Frequency weighting: A, B, C and Z
• Time weighting: Fast (125 ms), slow (1 sec) and impulse (35 ms), decay (1500 ms)
• adjustable data-recording interval from 1 s … 24 h
• 1/1 octave band filter (optional 1/3 octave band filter upgrade)
• incl. ISO Calibration Certificate
