The class 2 data logging SPL meter is an optimal sound level meter for measurements at workplaces, construction sites, in traffic, airports, etc. The SPL meter is a class 2 device and is equipped with an octave band frequency filter. The SPL meter can optionally be upgraded with a 1/3 octave band filter.

- Accuracy class 2
- 1/1 octave band included
- 1/3 octave band optional
- A, B, C & Z frequency weighting
- Fast, Slow, Impulse and Peak time weighting
- Statistics function
- Including class II sound calibrator
- Including calibration certificate for sound level meter
- Including calibration certificate for sound calibrator

PCE-428 is a class 2 data logging SPL 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 SPL meter has a large easy-to-read illuminated LCD screen that displays the sound pressure level (SPL) numerically and graphically in real time. The SPL meter 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
