Product Photo (DR-7100 Portable Data Recorder)



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.

The DR-7100 has useful functions to measure surely and quickly the sounds and vibrations in question on site, even at a narrow or a high place, and even there is no time to spare.

For example…



  • Data recording with high speed, high accuracy (4ch 40 kHz range 24-bit)*1
  • Equipped with a connector for a rotation pulse input
  • Available for SDHC 32 GB
  • Speedy setup by TEDS sensor
  • Compact body of A5 size
  • 2-unit synchronicity function (option)

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



Simultaneous recording of sound & vibration and rotation speed

8ch Data recording by 2-unit synchronicity function


2-unit synchronicity function of DR-7100 allows 8ch data recording. The amount of recording time can be reduced.
(Unit synchronicity function DR-0730 and cable for unit synchronicity DR-0703 are required.)

* Note: If a TEDS supported sensor made by other companies is used, TEDS information may not be read depending on the type of a TEDS tip included in a sensor.

1. If you are considering the purchase of a TEDS sensor made by other companies, please consult to the manufacturer or dealer of the TEDS sensor, and perform the operation check.

2. When you want to use a TEDS sensor you already have with the TEDS supported measurement instruments made by Ono Sokki, please perform the operation check with a demonstration product of Ono Sokki. (Please consult your nearest distributor or Ono Sokki sales office nearby.)
