The HD9101 and HD9102 sound level generator is a battery-fed portable sound source, suitable for calibrating sound level meters (portable and laboratory models) and acoustic measuring stations. It’s possible to calibrate directly 1” microphones and, by means of a proper adapter (model 9101040), also 1/2” microphones; the mechanical dimensions are in accordance with standards IEC 61094-4 (“Measurement Microphones, Part 1: Specifi cations for Laboratory Standard Microphones”) and IEC 61094-4 (“Measurement Microphones. Part 4: Specifi cations for working Standard Microphones).
