Professional sound level meter ideal for measurements for workplaces which are outdoors, e.g. at airports, on building sites, in road construction etc. with broad access to spectrum thanks to the highly-accurate 24-Bit A/D converter

floating point evaluation for higher level of accuracy and better stability
the optimised analogue frontend switch reduces the ambient noise and increases the linear measuring range
a specially-developed algorithm permits a compliant dynamic range of more than 120 dB! (SW 1000: > 123 dB; SW 2000: > 122 dB)
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
LN statistics and display of the graph showing the progression of time
user-defined integral interval measurement up to a maximum of 24 hours is possible
frequency weighting (filter) A, B, C, Z
time interval during measurement: F (fast), S (slow), I (pulse)
freely-definable limits for the output of an optical alarm signal
Peak Hold Mode to capture peaks
octavo function for targeted sound analysis
TRACK function with graphic display of a measurement
