توضیحات
Features
- One-touch simple calibration.
- Output range can be arbitrarily set in the range of from 0-1 mg/l to 0-3 mg/l in the field.
- Line segment output is available for output signals.
- Easy confirmation of inter-electrode applied voltage/current characteristic (plateau characteristic). This allows understanding of the detailed sensor characteristics in the application.
- Rotating electrode/ceramic bead cleaning has been improved to realize further effective and continuous automatic cleaning.
- Easy-to-maintain (-clean) cell construction.
