Dissolved Oxygen Sensor DO Meter Water Measuring Instruments Water Quality Monitor Fluorescence Online Analyzer

Short Description:

These sensors utilize proprietary fluorescent-sensitive materials. They do not consume oxygen, are insensitive to water velocity, and require no electrolyte addition, significantly reducing maintenance requirements. They also feature a built-in temperature compensation module and support RS485 digital signal output. Their robust anti-interference capabilities and excellent long-term stability enable rapid integration into aquaculture and environmental water quality measurement and control systems.
