The unit 05000 - sound level calibrator is used to calibrate the various equipment.
Sound pressure level - 94dB.
Frequency - 1 kHz ± 1,5%.
Diameter calibrated microphones - 23.77 mm ± 0,02 mm 13.2 mm ± 0,05 mm with an adapter (1/2 inch).
Weight - 0.35 lbs.
Calibrators 05,000 are commonly used in the calibration of individual audio meters portable or laboratory devices and integrated acoustic instrumentation. Furthermore, with 05,000 possible to calibrate the transmission coefficients separate microphones (1-inch and 1/2-inch microphones).
The main error that has been committed calibrators 05000 is ± 0,3 dB. In this case, THD less than 1%.
Calibrator 05000 operates at temperatures from -10 ᵒ C to +50 ᵒ C.
