Dissolved Oxygen Controller
Description
Dissolved Oxygen Controller
Dissolved Oxygen Controller is suitable for accurate measurement and control of dissolved oxygen in all kinds of weather and complex industrial environment.
Introduction
- 128 * 64 dot-matrix LCD display, switchable in Chinese and English, IP65 protection level, all-weather stable operation
- simple menu design, simple and convenient operation, graphical prompt, beautiful and clear interface
- software digital filtering is adjustable, with enhanced hardware resistance to interference, making measurements more stable and adapted to complex industrial environments
- global access power supply 85~260VAC, but also customized DC model 18 to 36 VDC
- RS-485 digital interface, MODBUS-RTU communication protocol, read and write two-way communication, can achieve remote complete control of the instrument
- The is compatible with two types of electrodes, 400nA or 80nA
