The DR-7100 is a portable data recorder for acoustic and vibration with high accuracy.

In recent years, we are living surrounded by the equipments which make noise and vibration such as a car, a railroad, a household electric appliance and a wind power. These equipments are now required for “more quiet” “more comfortable” and “lower vibration” than ever.

The DR-7100 greatly helps to make such comfortable acoustic environment by recording sound and vibration on site with ease and high accuracy.

Feature

  • •Data recording with high speed, high accuracy （4ch 40 kHz range　24 bit *1）

  • •Dynamic range of 90 dB or more

  • •Equipped with a connector for an rotation pulse input

  • •Available for SDHC 8 GB

  • •Speedy setup by TEDS sensor

  • •Compact body of A5-size

  • •2-Unit synchronicity function （option）

*1 40 kHz　range: option （20 kHz band frequency: standard）
