Bruel & Kjaer 2203 Sound Level Meter

Manufactured by: Bruel & Kjaer / Denmark

Model No. Precision Sound Level Meter Type 2203

Extracted from B&K product news:
The compact, battery-operated Type 2203 Sound Level Meter, is a high-precision portable instrument, which has been designed to completely fulfill the proposed international IEC standards for Precision Sound Level Meters. It is mainly intended for the quick and accurate measurement of noise from traffic, and within factories and buildings as the instrument gives a direct scale reading in db sound level. The measuring range is 22db to 134 db, and it is accurate within +/- 1db.
The instrument can be connected to external 1/1 or 1/3 octave filters, converting it into a frequency Analyzer, and by connecting the output to a level recorder an automatically paper-recorded reading can be produced.
A linear frequency range of 20c/s to 20,000 c/s is also included, which facilitates the use of the instrument, not only as a sound level meter, but as a battery operated preamplifier for voltage and vibration measurements.
The sound level meter is transistorized for low power consumption and equipped with a precision condenser microphone (B&K type 4131).
