RION Level Recorder LR-07 | Nihon Denkei India Private Limited

Ease of Use in a Clever Package

Records sound level, vibration level or DC voltage. External control is possible for pen, paper feed and marker functions. Operates in sync with level processing equipment.

Level Recorder

Model:

LR-07

Maker:

RION CO.,LTD.

Features

Records sound or vibration levels
Records DC voltages
External control of pen, paper feed, and marker functions
Measurement with coordinated paper feed
Operates in sync with level processing equipment

Versatile external control

Pen movement, paper feed start/stop, marker operation, and paper feed rate selection can be controlled from other equipment.

Paper-feed controlled measurement

When the measured sound or vibration level exceeds a certain threshold, paper feed can be automatically increased for easier reading of the recorded information. This saves paper and is useful for example in train and airplane noise measurements or other situations where non-continuous events are to be recorded.
