01DB Noise dosimeter

WED noise dosimeter and associated dBLEXD software offers the perfect solution for assessing individual exposure to noise at a workstation, in compliance with European directive 2003/10/EC and many international standards BS EN 61252.
Bluetooth wireless technology enables users to analyze the collected data from remote, without disturbing the operator at the workplace during the measurement.

Standard requirements

WED dosimeter is a portable ergonomic equipment that consists in a storage system  and transference of data:

  • simultaneous measurement of the curves A and C
  • exposure calculation TWA 8h, Dose and Thought out Dose
  • measuring range from 40 to 140dB (A)
  • scales: 40 a 120dB(A) / 60 a 140dB(A)
  • peaks of 135,137 and 140 dB.
  • battery life up to 50h

Wireless control dBWED

Using a notebook or a computer, you can configure the WED settings with the use of the dBWED software and analyse them in real time at a distance, enabling the user to monitor the measurement at a safe distance from the agents:

  • simultaneous control of diverse WED dosimeters
  • management of measurement setups
  • recording of the measurement files
  • viewing in real time of the measured data
  • voice and written comments

dBLexd software

The processing data dBLexd software meets the requirements of all the national and international standards:
