Deskripsi produk
DESCRIPTION
Class II Condition monitoring sound level meter / Data logger / USB interface / Measuring range 30 ... 130 dB / LC display / Including software / Memory for up to 32700 measured values
The condition monitoring sound level meter is particularly suitable for measuring noise pollution in the field of industrial, health, safety and environmental monitoring. The sound level meter has a logger function, which enables the storage of up to 32700 measured values. This makes it ideal for long-term monitoring. The PCE-322A sound level meter can be connected to the PC with a USB cable. A live measurement is also possible with the sound level meter and the data can be viewed directly and evaluated. The software offers data representations in graphic formats and tables. This data can be transferred to MS Excel, for example. The data logger has an analog output and offers additional features that are unique in its class.

Class II sound calibrator with different sound pressure levels

The calibration frequency for the class II sound calibrator is 1000 Hz and is a sinusoidal shape. Compared to other calibrators, this class II sound calibrator has three adjustable sound pressure levels. 94 dB, 104 dB and 114 dB are available and can be selected by pressing a button on the class II sound calibrator. This means that an additional 104 dB sound pressure level is available. With an accuracy of ± 0.4 dB, the class II sound calibrator is particularly precise. This means that the Class II sound calibrator can be used to check sound measuring devices for their accuracy and, if necessary, to adjust them. The class II sound calibrator can optionally be equipped with an ISO certificate.

With a battery life of 50 hours, the class II sound calibrator has a particularly long operating time. The integrated automatic switch-off automatically switches off the class II sound calibrator after 20 minutes of inactivity.
