SV 36 Class 1 acoustic calibrator features an OPTIC SENSOR that detects microphone presence and turns on/off the calibrator automatically.
The SV 36 acoustic calibrator is a small, portable dual-range Class 1 device (sound source). Powered by two AAA batteries, it contains a loudspeaker producing acoustic pressure of defined level 94 db & 114 dB at frequency of 1 kHz.
SVANTEK Calibrators are based on the reference sensors and microprocessor controlled signal source including digital SOUND PRESSURE LEVEL, STATIC PRESSURE and TEMPERATURE compensation.
Unlike many others, the SVANTEK calibrators feature a ROBUST HOUSING that gives the comfort of a secure grip to the user.
The accuracy of acoustic calibrator should match the class of the sound level meter. A CLASS 1 (SV 33A or SV 36) or CLASS 2 (SV 34A) calibrator should be used, depending on the class of instrument.
The user interface of the calibrator is equipped with a PUSH BUTTON and a LED diodes signalizing calibration and battery faults.
SV 34A Class 2 Acoustic Calibrator generates reference signal of 114 dB at 1 kHz and is designed to calibrate Class 2 sound level meters and noise dosimeters with1/2 microphones.
Thanks to the MEMS technology the calibrator presents the best price versus performance ration in a current noise market.
