Sound Calibrator “TYPE 2127”

SKU : #340

Low cost calibrator which is small, lightweight and easy-to-use
Type 2127 is a sound calibrator with high accuracy feed-back control method. It has been developed under the concept of “provide low cost calibrator which is small, lightweight and easy-to-use” and has many unprecedented features.
It complies with JIS C 1515:2020 Class1, IEC60942:2017 class1 and uses stable condenser microphone as a control sensor.
Since it strictly controls generated sound pressure level in real-time, the possibility of errors due to changes in atmospheric pressure or microphone insertion loss are very small, and the accuracy and stability are unmatched despite its small size.

“Features”
● Pursuant Standards: JIS C 1515:2020 Class1, IEC60942:2017 class1
● Dedicated adapter is attached to it, therefore it can be used for not only sound level meter calibration but also for 1 inch, 1/2 inch or 1/4 inch microphones.
● Nominal generated frequency and sound pressure level are 1000 Hz, 94 dB
● There is no worry about calibration at wrong sound pressure level because battery depletion is warned by blinking LED and stopping the sound.
