Deskripsi produk
DESCRIPTION
Decibel meter (badge type) according to IEC 61252:2002 / Measuring range 70 ... 140 dB / Crocodile clips / For use in occupational safety / Battery life >15 hours / USB interface / Key lock / Frequency weighting A, B and Z / Optional with ISO calibration certificate
The decibel meter (badge type) was specially developed for measuring noise exposure in workplaces and complies with the IEC 61252:2002 standard. With a measuring range of 70 … 140 dB and a frequency weighting of A, B and Z, the noise dose meter is ideal for this. The time weighting on the noise dose meter can be selected between fast, slow and impulse. With the built-in 470 mAh battery, the noise dose meter has a runtime of >15 hours.

Up to three virtual noise dose meters can be set in a decibel meter (badge type). This has the advantage that up to three measurement standards can measure simultaneously. The display of the noise dose meter shows up to 14 measurement windows that can be set individually.

The data transfer from the decibel meter (badge type) to a PC takes place directly via the charging station. The recorded measurement data can be read out and analyzed with the software for the noise dose meter. In addition, all settings for the noise dose meter can be made via the software. Another special feature of the noise dose meter is that the charging stations can be coupled with each other. This has the advantage that several noise dose meters can be charged via one power pack. Up to four noise dose meters can be charged simultaneously per power supply.

For optimal support and positioning, the decibel meter (badge type) is attached to the work clothing of the respective employee with two crocodile clips. The distance between hearing and the noise dose meter should be between 10 and 15 cm (3.9 and 5.9").
