If you have a soundproof room, the BAS-200 Bio-Acoustic Simulator performs dependable daily calibration checks of the CCA-200 audiometer as required by OSHA 29 CFR 1910.95.
Your testing equipment needs to be calibrated daily. Depend on the BAS-200.
Because the BAS-200 is powered by the Benson Medical Instruments audiometer, there is no need to worry about battery life. Connecting the response switch to the BAS-200 returns the system to subject testing.
The BAS-200’s advanced design simplifies the daily check and offers greater reliability and repeatability compared to battery-powered units.
