SH-DO200 Dissolved oxygen digital sensor
Overview
The SH-DO-200 Dissolved Oxygen digital sensor uses the fluorescence method to detect dissolved oxygen in the water column, with a built-in temperature sensor that automatically compensates for the effect of temperature on the measurement. The sensor uses RS485 interface and standard Modbus protocol.
Product features
- No need to replace the dissolved oxygen film and electrolyte, low maintenance
- Fast response time with fluorescence detection technology
- Internal storage of calibration data
- Corrosion-resistant housing, waterproof grade IP68, can work underwater for a long time
- RS485 communication interface, standard Modbus protocol for easy integration.
