    采用直观的两键式操作,使 CEL-240 操作简单易于使用,适用于各种噪声测量场合。通过采用最新数字技术,使得 CEL-240 具有极高的可靠性,确保高水平的测量精度和性能。仪器结 构紧凑坚固耐用。在具有高清晰显示器的仪器中,此款仪器售价最低。CEL-240 能够显示噪声水 平的时间历史值,可方便地对当前的噪声环境进行评估。

特点:

● 操作简单
● 坚固耐用
● 高清晰度显示
● 采用最新数字技术
● 完全符合 IEC 61672 标准
● 测量范围大
● 最大值保持功能
● 自动校准
● 电池供电时间超过 35 小时
● 质保期两年
● USB 接口

性能:

CEL-240 的用户界面非常简单,使用屏幕底部的两个‘软按键’表示选项,使得仪器非常易于使用。声压级和 最大声压级可同时以数字柱形图或者以独特的时间历史方式显示(显示在右边)。 通过按键可非常简单地改变仪器设置。既可设定频率计权(A 或 C)又可设定时间计权(快,、慢或脉冲)。 仪器的校准在简单不过了,CEL-240 可自动识别应用的校准器,使用单个按键调整校准。仪器可显示瞬间和最大声压级。这些数值,及图表化的时间历史数值都可通过按 键重新设置。

dB24 软件: 这个可选软件可实时地将通过 USB 输出到个人电脑上的数据进行记录和存储。 声压级由 dB24 软件按秒钟存储成数据文档,并与基于 PC 的电子表格软件兼 容。dB24 提供一个了简单可行的方法,记录在规定时间区间内声压级时间历史 数据。
