Description
Seametrics DO2 Smart Sensor is the next generation in trouble-free oxygen sensing design. Utilizing fluorescence of a stable, immobilized ruthenium-based film matrix, the sensor provides precision optical transmission and detection to measure oxygen concentration in the fluid outside of the sensor. Equipped with integrated datalogger and Aqua4Plus software, this sensor provides convenient, high-quality data to the user.
Seametrics DO2 Features
- Measures and records dissolved oxygen and temperature internally
- Modbus® RTU (RS485)
- 260,000+ record non-volatile memory — no data loss in the event of a power failure
- Programmable warm-up time
- The sensor does not require water movement, flow, or frequent cleaning
- Does not require frequent calibration
- 1.66? diameter—fits easily in 2-inch wells
- Measures dissolved oxygen and temperature
- Fluorescence sensor technology
- No membranes, fill solutions, replacement caps, or cartridges required
- Includes new Aqua4Plus control software for setting up flexible recording sequences, retrieving data, monitoring real-time data, and viewing collected data
Applications
- Dam discharge monitoring aquaculture
- Leachate monitoring (Landfill)
- Long-term surface water monitoring
- Monitoring remediation performance
- Municipal and industrial water treatment facilities
