Portable Data Recorder For Acoustics & Vibration
DR-7100
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…
Features
*1: 40 kHz range: option(20 kHz range: standard)
Example
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.)
