IEC 60942 1級手持式聲級校準器，適用于1/2 Hz的1/2“麥克風用于聲級計和其他聲音測量設備
Larson Davis CAL200聲級校準器是用于校準聲級計和其他聲音測量設備的電池操作精密麥克風校準器。它可以以1 kHz的頻率提供94.0或114.0 dB(開關可選)的輸出電平。KLIXON溫控器
它已被設計用于現(xiàn)場和實驗室使用，并且準確性已經(jīng)被校準到可追溯到國家標準與技術研究所(NIST)的參考。
Larson Davis CAL200具有獨立于電池狀態(tài)的穩(wěn)定的聲壓。此外，Larson Davis CAL200將自動關閉以保持電池并保證穩(wěn)定的輸出。FLOYD BELL嗡鳴器
