LDO02Water Monitoring
Fluorescent Dissolved Oxygen Sensor
Fluorescent dissolved oxygen sensor measures dissolved oxygen concentration from 0 to 20 mg/L (0–200% saturation) and temperature, with accuracy ±3% FS and ±0.5°C at 25°C. It outputs via RS485 with standard Modbus-RTU protocol and features automatic temperature compensation. Suitable for water treatment, aquaculture, and environmental monitoring applications.

LDO02 questions
What ranges are available for the LDO02?
Standard coverage is 0–20mg/L (0–200% saturation). Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the LDO02 be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the LDO02 from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right fluorescent dissolved oxygen sensor for your process?
