Our premium portable SL-4013 environmental measuring instrument volume is durable and designed for a very wide area of applications. It makes possible a fast situation examination just like a regular check measurement. The measurement of noise wins meaning within all ranges, particularly to the statement of stress factors in office, workshop, flight and road noise. This equipment permits a weighting after A and C.
Evaluation curves (A, B and C after International Electronical Commission DIN 651) are the curves of weighting filters to be applied to the sound pressure signal. They are determined to represent a similar dynamic response for a completely volume as the human ear. Likewise the equipment weights after 2 different time periods. The device has a RS-232 interface to transfer data to any PC. Software and cable (SW1) are available in our shop.
A further big advantage of this noise level measuring instrument is its large measuring range from 31.5Hz to 8.0 GHz. The meaning becomes clearly evident from the curves of same volume perception (Isophonen).
