Professional sound level meters of class I and class II in premium quality.

Features

• Ideal for measurements for workplaces outdoor, e.g. at airports, on building sites, in road traffic 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
• 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 function to capture the peak value
• Octavo function for targeted sound analysis
• TRACK function with graphic display of a measurement
• Calibration mode (with optional calibrator)
• Trigger mode: Analogue signal to switch the device on or off with 3.5 mm plug
• Automatic measurement for timer function is possible
• Selectable frequency for recording measurements: 10, 5, 2 Hz
• Operating languages: GB, DE, FR, ES, PT
• Delivery in robust transport case
• Option of fitting a stand on the rear of the housing, 1/4" thread
