Features
1. Large display, standard 485 communication, with online and offline alarm, 98*98*130 meter size, 92.5*92.5 hole size,3.0 in chlarge screen display.
2. Fluorescent dissolved oxygen electrode adopts optical physics principle, no chemical reaction in the measurement,no influence of bubbles, aeration/anaerobic tank installation and measurement are more stable, maintenance-free in the later period, and more convenient to use.
3. Carefully select materials and strictly select each circuit component, which greatly improves the stability of the circuit during long-term operation.
4. The new choke inductance of the power board can effectively reduce the influence of electromagnetic interference, and the data is more stable.
5. The design of the whole machine is waterproof and dustproof, and the back cover of the connection terminal is added to extend the service life in harsh environments.
6. Panel/wall/pipe installation, three options are available to meet various industrial site installation requirements.
