Our new portable TMT-85 environmental meter sound level meter is compact, robust and very easy to use. It enables a quick situation check as well as a regular control measurement. 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.
This device operates with sound leveling according to A. The rating curve A according to IEC / DIN 651) is the curve of the evaluation filter which is applied to the sound pressure signal. It is supposed to represent a similar frequency behavior for the human ear for a certain time.
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).
The device has a "HOLD function" to keep the current measured value on the display and a Min- and Max-function to keep the minimum / maximum measured noise level on the display. Thus, it is very simple to get e.g. a measurement over 10 minutes and the maximum / minimum value. Other comfort features include backlighting and automatic shutdown when not in use.
