Overview
The BI-680 industrial online dissolved oxygen meter is an economical industrial online dissolved oxygen meter of the BANTE brand, which supports 1 or 2 point button calibrating and provides 4 to 20mA signal output. The meter is suitable for monitoring oxygen concentration or Saturation of water quality in the water treatment and aquaculture industries.
Features
1. Economical industrial online dissolved oxygen meter, support 1 or 2 point calibrating.
2.4 to 20mA signal output, can be set corresponding Measured value.
3. High or low alarm limit setting, can customize the amount of hysteresis.
4. Manual salinity and atmospheric pressure compensation to improve instrument Measurement accuracy.
5. Automatic temperature compensation, eliminate the data deviation caused by temperature difference.
6. Manual temperature calibrating, improve instrument temperature Measurement accuracy.
7. RS485 communication output, in line with industrial instrumentation communication specifications.
8. The built-in system menu can customize 10 functional parameters such as the number of calibrated points, salinity compensation and atmospheric pressure coefficient, and alarm limit.
9. One-click reset (RESET) automatically restores the meter to factory default settings.
Principle
Measurement accuracy is ensured by means of dissolved Oxygen electrode measurement of dissolved Oxygen concentration in water, combined with automatic temperature compensation, manual salinity and atmospheric pressure compensation to eliminate environmental factors. Communication interface for signal output and data transmission.
Applications
Water treatment and aquaculture industry
