Sound measurement

Sound level meter for noise measuring.

• Delivered in a hard carrying case
• Multi measuring functions: Lp: Standard sound level measuring function, Leq: Energy equivalent sound level measuring mode (type A), Ln: Shows the deviation from a pre-defined limit in %
• Selectable methods of evaluation: A: As sensitive as the human ear, C: Sensitive for noisier environmental, conditions, where there are machines, plant, motors etc., F: For areas where sound intensity does not vary
• Function to set limits: Programmable target value for go/no-go test values
• Track function for continuous recording of variable environmental conditions
• Peak Hold Mode to capture peaks
• Internal memory for measured values, for 30 measurements. Can be displayed on the PC
• Data interface RS-232, included

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.

• Different sound pressure levels can be selected, such as, for example, Laeq, LcPeak, LaF, LaFMax, LaFMin, SD, SEL, E
• The optimised analogue frontend switch reduces the ambient noise and increases the linear measuring range
• 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 Mode to capture peaks
• 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
• Measured value recording frequency selectable: 10, 5, 2 Hz
• Data transfer using MicroSD (4 GB), RS-232 or USB
• Option of fitting a column on the rear of the housing, ¼ thread
