Volume meter with data logger

from 31.5 Hz to 8000 Hz. With this professional sound level meter, you can carry out a wide variety of volume measurements. The device has a precision condenser microphone and a calibration circuit for adjusting the device with a separate calibrator.

In organ building, it is also ideal for documenting the volume of individual stops for before and after comparisons. Also useful for fixing an independent volume value that is not dependent on individual hearing perception.

The measured value memory for 32000 measured values and the USB interface for data transfer to the PC and the enclosed evaluation software for Windows 98/ME/2000/XP allow you to record the measured values over longer periods of time and evaluate them on the PC.
Delivery includes battery, case and windshield for microphone

Here is some more information on volume measurements:
In medicine, the threshold for possible hearing damage is a noise exposure of 85 decibels (dB), the pain threshold is 120 to 130 dB - roughly equivalent to the noise of a jet taking off 100 meters away. In homes, the noise level is typically 40 to 50 dB, in offices up to 65 dB. In road traffic, 85 dB is quickly reached, discotheques and rock concerts are often significantly louder at up to 110 dB than a jackhammer at 100 dB - every three decibels more doubles the strain on the ear.

When measuring noise, please note that the human ear perceives noise differently depending on the time of day. Noise at night or during rest periods is perceived as much more disturbing, even though it has the same decibel value as at times when there is more ambient noise.

This device provides you with good information and comparative values, which you can also record over a longer period of time using the data logger. In the event of legal disputes, however, only measured values from publicly sworn experts are normally recognized.

Please note the very attractive special price!
