RS485 Modbus Optical DO Sensor Fluorescence Dissolved Oxygen Probe with IoT 4G WiFi LoRa MQTT
Product Vedio
Product Features
1. Optical dissolved oxygen membrane head: Compared to membrane methods, it is maintenance-free and does not require regular electrolyte replenishment.
2. Fast reaction time: Data stabilizes within 10-15 seconds after power-on, making it particularly
suitable for online dissolved oxygen monitoring in wastewater treatment.
3. Thick, wear-resistant membrane head: With a service life of up to 3 years, it is particularly suitable for harsh environments such as aquaculture. It also supports secondary membrane head replacement and custom brushes.
4. Simultaneously outputs dissolved oxygen, temperature, and saturation values.
5. Supports atmospheric pressure and salinity compensation, allowing use in areas with different altitudes and salinity levels while maintaining accuracy.
6. Supports secondary calibration to maintain data accuracy.
