产品简介：

DC1 12 是一台高性能倍频程噪声剂量分析仪，适合按照标准  2003/10/CE进行 工人的声暴露听力保护测量。

应用  同时进行工人在工作环境下的声暴露评价和进行PPE ( Personal ProtECtive Equipment 个人保护装备)的测试。

技术指标

•   噪音剂量计符合标准EN 61252，和 2003/10/CE。

•   用于PPE ( Personal Protective Equipment 个人保护装备)的倍频程实时频率分析。

•   内置存储(64 MB)保存测试结果的时间历程数据。

•   透视参数：声暴露测量时间小于暴露时间的的声暴露评价。

•   电池 (16 h) 供电和通过USB供电。

•   Capture Studio 软件：数据下载 (USB 端口)，实时通讯，图表和列表显示。
