瑞士制造 精密品质

经优化的量测麦克风(传声器)在 5 Hz – 20 kHz 范围内具备平坦的自由场响应。特定型号最大可测 155 dB 的声压级。

全指向性量测麦克风由 48V 幻象电源驱动并内含电子数据表单。声级计自动感应侦测(ASD)功能可自动读取这些数据,进而识别如麦克风型号,灵敏度和校准数据。这确保了精确的测量结果。

精确. 通用. 可靠.

  • 全指向性自由场麦克风
  • 1 级频率响应的精密传声器

XL2/XL3 分析仪量测麦克风

量测麦克风由48V幻象电源驱动,内含电子数据表单。声级计的自动感应侦测(ASD)功能自动读取这些数据,如麦克风型号,灵敏度和校准数据。这确保了精确的测量结果。

麦克风包含前置放大器,有很高的动态量测范围与很宽的频率范围且内部噪声非常小。麦克风可通过 ASD 缆线连接到音频分析仪或声级计,以便于远程量测或减少声学反射。M2230,M2211,M2215 由 MA220 前置放大器和专用咪头组成。M2340 由 MA230 前置放大器和咪头组成。

特性:

  • 全指向性,自由场麦克风
  • 48 V 直流幻象电源
  • 内置电子数据表
  • 频率范围 5 Hz – 20 kHz
  • 单独的频响曲线数据以 Excel 档案保存
  • 可选购校正证书

低噪声量测麦克风 M2914

M2914 量测麦克风拥有 6.5 dBA 的极低本底噪声,它专为低声压级的声学测量设计。

产品编号:600 040 240
(需额外搭配 ICP 转 ASD 适配器(产品编号:600 010 223)才能在 XL2/XL3 声级计使用)

    I’ve been using the XL2 for over 15 years for short-term and long-term measurements in all kinds of indoor and outdoor environments all across the country. The meter gets me what I want, when I need it. It’s not only the best value for acoustical measurements, it’s the best tool period. I bet my company and reputation on XL2 results and it has not let me down. You would be crazy not to consider adding NTi instruments to your toolkit.

    We at Constructure GmbH use two XL3 sound level meters for noise monitoring during demolition work. We are very satisfied with these highly user-friendly instruments, the online monitoring in the MeasurEye Cloud, the good advice and qualified support. Factory calibrations at NTi Audio are also handled very smoothly and without complications.
