The measurement of noise is gaining importance in all areas, especially in the determination of stress factors in the office, workshop, aircraft noise and noise.
Our portable TMT-SL1361 sound level meter is a sophisticated and robust sound level meter for a very wide range of applications, including evaluation software for PCs and notebooks. It provides a quick situation check as well as a regular control measurement and documentation option due to the integrated memory for 4700 measured values and the calendar function.
Of course, the measurements can also be transferred to a PC / notebook in real time using the software and USB connection cable. It is also possible to transfer up to 4700 "in field" measuring results, which were recorded in the internal memory of the device", to the PC / notebook, evaluated and printed out. The interface is a USB interface and is included.
This device allows a weighting according to A and C. Rating curves (A and C according to IEC / DIN 651) are the curves of evaluation filters which are applied to the sound pressure signal. They are supposed to represent a similar frequency behavior to the human ear for a certain volume. The device also has a time weighting of the noise level. The weighting of the time in the measuring process is also provided by the FAST and SLOW option. FAST describes the real-time operation, SLOW supplies the average value of the last second.
Another great advantage of this noise level meter is its large measuring range from 31.5Hz to 8.5kHz and from 30dB to 130dB. The meaning is clearly evident from the curves of the same volume perception (isophones). On the device the measuring ranges 30-80, 50-100, 60-110 and the automatic range selection 30-130dB can be set for a more accurate measurement of the ranges. If a measuring is under/over the range, this is signaled by the device in the display and the measuring range can be adapted as required.
