Class 1 Sound Level Meter ST -12D

操作及螢幕顯示全面升級，加入塹新錄音功能，更能滿足工程以外的用途。音頻測量範圍廣寬，達到27-140dB，適用於嚴格的噪音測量。

界面全面升級，比過往型號及同級品牌更易用及具有各種輸出選項，ST- 12D可以通過遙測進行控制，並實現外部系統集成。 ST-11D中的附加數據記錄和錄音功能有助於長期數據記錄。輕巧，便攜，而外殼及保護箱完美成型，整體尺寸縮減20%，但功能卻不減損﹐令ST-11D 在眾多產品中，以卓越的性能屹立於市場之頂端。

ST-12D complies with the Class 1 IEC 61672-1:2013 standard, designed for occupational noise measurement and research. It features a wide measurement range of 25 to 140 dB and is capable of measuring parameters such as Leq, Lpeak, Lmax, Ln, and more. The ST-12D also supports a spectrum analyzer with optional 1/1 and 1/3 octave band filters, enabling real-time frequency analysis for precise noise assessments.

初步決定是否需要噪音計作評估：

兩人相隔2米距離，需要大聲呼喊才可溝通
器材屬於勞工署的高噪音機械名單內
在工作環境下產生耳鳴及耳壓不適
密閉空間內的高噪音環境（機房、生產器械廠房）

勞工署規例第3(3) 條, 噪音評估報告

評估完成後的28天內，將副本送交勞工署
