Description

• Ideal for measurements for workplaces outdoor, e.g. at airports, on building sites, in road traffic etc. with wide frequency access
• Modern microcontroller architecture for increased stability and accuracy
• A specially-developed algorithm permits a compliant dynamic range of > 123 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 peak value
• Octave function for targeted sound analysis, can be expanded to 1/3 octave through the purchase of a licence
• TRACK function with graphic display of a measurement
• Calibration mode (with optional calibrator)
• Trigger mode: external start/stop of measurement via 3,5 mm connector
• Automatic measurement for timer function is possible
• Operating languages: EN, DE, FR, ES, PT
• Option of fitting a stand on the rear of the housing, ” thread
• Delivery in robust transport case

• Technical Data
