SW Sauter Sound Level Meter

Sauter's SW sound measuring meter is a portable, easy-to-use device perfect for outdoor environments, airports, building sites and within the construction industry. This device has broad access to spectrum thanks to a highly-accurate 24-Bit A/D converter.

The SW has an optimised analogue frontend switch reduces the ambient noise and increases the linear measuring range. The specially-developed algorithm permits a compliant dynamic range of more than 120 dB! (SW 1000: > 123 dB; SW 2000: > 122 dB).

Floating point evaluation allows for a higher level of accuracy and better stability, whilst three profiles and 14 user-defined measurements can be calculated in parallel with different frequency and time weighting.

Different sound pressure levels can be selected, such as, for example, Laeq, LcPeak, LaF, LaFMax, LaFMin, SD, SEL, E, whilst LN statistics and display of the graph show progression of time. The SW includes user-defined integral interval measurement up to a maximum of 24 hours.

SW sound meters come with a wide range of features including a frequency weighting (filter) A, B, C, Z, smart time interval during measurement: F (fast), S (slow), I (pulse) and freely-definable limits for the output of an optical alarm signal.

Functions include: Peak hold for capturing peaks in data, Octavo function for targeted sound analysis, and Track function with graphic display of measurement.
