DR-7100 Portable Data Recorder for Sound & Vibration

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

We are living in a world surrounded by increasing levels of noise and vibration, which can have serious effects on our health. The DR-7100 can record highly accurate and reliable noise and vibration information so that steps can be taken to reduce their impact. Compatible with a wide range of accelerometers, tachometers and acoustic sensors as well as with external analysis software and systems, the DR-7100 can form the heart of a comprehensive data logging system for noise and vibration measurements.

* 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.)
