Good product
It seems that the calibrator works fine. I use it to calibrate my iPhone mic. So I hope that discrepancy is minuscule due to the fact that I can’t fit the microphone inside the hole. Probably will buy separate noise meter to check what the difference is.

Ich habe mich für dieses Produkt entschieden, weil es im Vergleich zu anderen Produktion im gleichen Preissegment die Optionen sowohl für 1/2"-Zoll sowie 1"-Zoll Mikrofone/Messgeräte bietet. Ich besitze 3 Schallpegelmessgeräte, welche ich noch nie kalibriert bzw. überprüft habe: - Voltcraft / RadioShack Sound Level Meter (analog), 1"-Mikrofon - Monacor SM-2 (digital), 1/2"-Mikrofon - Amprobe SM-10 (digital), 1/2"-Mikrofon Die ersten Messergebnisse waren recht ermutigend: - Voltcraft / RadioShack Sound Level Meter (analog): stimmte exakt (+/- 0,3 dB) - Monacor SM-2 (digital), 1/2"-Mikrofon: stimmte einigermassen (+/- 1 dB) - Amprobe SM-10 (digital), 1/2"-Mikrofon: stimmte exakt (+/- 0,3 dB) Ich darf daher mit einer gewissen Wahrscheinlichkeit davon ausgehen, dass dieser Kalibrator selbst ausreichend genau kalibriert wurde. Wichtig ist, dass man darauf achtet, dass das jeweilige Mikrofon fest und bis zum Anschlag in der Kalibrator-Öffnung steckt. Es hat einen dünnen Gummiring zwei, drei Millimeter davor, welcher einen glauben lässt, dieser sei der Anschlag. Dem ist aber nicht so, dieser Gummiring muss mit sanftem Druck mit dem Mikrofon durchstossen werden bis zum dahinter liegenden endgültigen Anschlag. Wenn man nicht darauf achtet und das Mikro nicht wirklich fest einführt, sondern beim Gummiring aufhört ergibt sich durch den ca. 3mm grösseren Abstand ein Messfehler von ca. 2dB!

Pretty accurate

Even when turned off, it drains the batteries with ~1mA. So after each use, you have to remove the battery. Stability over time is questionable. When new, my UMIK-1 and an SPL meter readings were within 0.5dB of the 94dB level. Now, both are 3 dB off on both high and low level. So I'm afraid this calibrator is less stable than the measurement mics to be calibrated with this device.
