The 1562 Sound Level Calibrator is
a self contained unit for making accurate filed calibrations on
microphones and sound measuring instruments. It generates a precisely
known sound pressure level at five ANSI-preferred frequencies.
With its several frequencies, improved accuracy and built in oscillator,
the 16562 Sound Level Calibrator outperforms all other sound level
calibrators.
The 1562 Sound Level Calibrator will calibrate the GR 1565-B
Sound Level Meter, the 1560-P5, -P6 and P7 microphones, 1551 P1
Condenser Microphone system, 1560-P3 and 1560-P4. Thus the sensitivity
and response tests can be made at several frequencies on a variety
of instruments with microphones, including types 1551, 1561, and
1565-A Sound Level Meters, 1558 Octave Band Analyzers, 1564-A
Sound and Vibration Analyzer, 1555-A Sound Survey Meter, and 1525-A
Data Recorder.
The 1562 Sound Level Calibrator can also provide an electrical
output for tests on sound level related instruments without microphones.
An indicator lamp tells you if your sound level calibrator has
adequate batter voltage.
NIST Certification for the sound level calibrator is provided.
