  • Notes
  • The Brüel & Kjær model 2203 was the world’s first precision hand-held and transistorised sound level meter. Type 2203 is a highly accurate instrument for sound level measurements. To make it convenient for field and outdoor use, as well as for laboratory measurements, it is designed as a portable battery-driven and rugged unit equipped with high quality components.
    Used in conjunction with a suitable filter set (e.g. the Octave Filter 1613), the instrument can be converted into a handy and easily operated frequency analyzer.
    Measuring range with 1" B&K condenser microphone 4131:
    Sound Pressure Level 31...134dB
    Sound level (weighted) 22...134 dB
    Octave Sound Pressure Level 20...134 dB.
    Switchable weighting filters for A, B and C curves or linear measurements.
