DR-DO1 - Water quality sensor
Dragino DR-DO1 Dissolved Oxygen Probe
The Dragino DR-DO1 measures dissolved oxygen and temperature in ordinary water. It differs from the DR-DO2, which is designed for seawater.
Measurement Ranges
Dissolved oxygen concentration is measured from 0 to 20 mg/L with a resolution of 0.01 mg/L and an advertised accuracy of 3%. Temperature is measured from 0 to 50 °C with a resolution of 0.01 °C and an advertised accuracy of ±0.5 °C.
Submersible Installation
The probe can be placed directly in water. The documented maximum pressure is 6 bar, the cable is 5 meters long, and the required power supply is between 5 and 24 VDC. The advertised power consumption is less than or equal to 0.5 W.
Electrical Output to be Confirmed
Dragino offers two outputs under the same DR-DO1 family: variant A with a 4–20 mA current loop and variant B with RS485 Modbus RTU. The Shopify SKU does not specify A or B. Therefore, the output of the delivered hardware must be confirmed before connection.
Applications
The DR-DO1 is suitable for freshwater monitoring, ponds, water treatment, and installations requiring dissolved oxygen monitoring.
