600-000-394 - Overview

The NTI 600-000-394 battery-operated Class 2 Sound Calibrator is classified for the calibration of class 2 measurement microphones, sound level meters and other acoustic measurement equipment. This microphone calibrator delivers 114 dB at a frequency of 1 kHz..

The Sound Calibrator features a stable sound pressure independent of the battery condition. It guarantees a reliable output and will turn off automatically to preserve battery.

Applications for Sound Level Measurement
Ensure accurate measurements
Adapt the measurement microphone to the local environmental conditions, such as temperature, humidity, and air pressure
Verify the stability of the sound level meter

Please Note! 1/4" and 1/2" Class 2 Measurement Mics refer to the diameter of the mic capsule ! Not the actual mic size of the mic itself. The mic capsule docks with this calibrator in order for the unit to do its thing!
