測量30至130 dB的噪音水平
SM-100型數(shù)字聲級計(jì)適用于測量30至130 dB的噪聲級，準(zhǔn)確度為±1.5 dB。型號SM-100具有31.5 Hz至8 kHz的頻率、三種不同的dB范圍和1/2“電容話筒。SM-100有兩種頻率權(quán)重：“A"權(quán)重范圍為30至130 dB，而“C"權(quán)重范圍為35至130 dB。當(dāng)裝置設(shè)置為快速響應(yīng)時，四位LCD背光顯示屏能夠在0.5秒內(nèi)更新。型號SM-100具有數(shù)據(jù)保持、記錄/最小值、自動測距、自動斷電和50 dB動態(tài)范圍的功能。SM-100的緊湊尺寸使其易于操作和儲存。每個單元包括電池、手提箱、保護(hù)傳感器的黑色泡沫蓋以及使用說明書。SM-100是技術(shù)人員測量和記錄建筑物、音樂廳、劇院區(qū)域或房間以及工廠地面設(shè)備或機(jī)械附近聲級的理想選擇。
