ONO SOKKI SC-2500A (Class 1) Sound Calibrator
Harga dapat berubah sewaktu-waktu mengikuti perkembangan kurs rupiah terhadap mata uang asing lainnya sehingga sangat mungkin terjadi adanya perbedaan harga yang berlaku dengan harga yang tertera pada website kami.
SC-2500A Sound Calibrator (Class 1)
The SC-2500A uses the sound pressure feedback control method to control fluctuations in sound pressure caused by static pressure, it can generate a stable sound pressure even if the operating environment changes.
Cost-effective model.
Accommodates 1/2″ Microphones and 1/4″ Microphones (optional adaptor required).
Important points for using the calibrator
The calibration sound pressure level may be different depending on the type of microphone. Be sure to check the calibration sound pressure level in the instruction manual before performing calibration.
A Class 1 Sound Calibrator is recommended for a Class 1 (or type 1) Sound Level Meter and microphone.
Periodical calibration of a sound calibrator is necessary to secure its performance. Calibration once a year is recommended. Please contact us for more details.
