General Radio 1982 Type 1 Sound Level Meter/Analyzer

The Genrad 1982 is a Sound-Level Meter & Analyzer you can use without plug-in filters or costly accessories, to make A, B, or C weighted sound-level measurements from 30 dB to 140 dB . . .octave-band analyses in 10 bands from 31 .5 Hz to 16 KHz.. .and peak or impulse noise measurements.
 

The 1982 conforms to ANSI Type 1 and IEC sound-level meter standard 651. In addition, it uses a single attenuator, allowing you to set the range desired, switch on the instrument, and read the measured level from either the digital or analog display. This eliminates the confusion of a two-attenuator system.


Features:


  • Digital and analog displays
  • Digital display captures and holds maximum sound level for accurate readings
  • 50-dB analog meter scale has 1-dB linear calibration
  • Ideal for OSHA measurements
