SZ508-AWater Monitoring
Self-Cleaning Dissolved Oxygen Sensor
Measures dissolved oxygen from 0–50 mg/L or 0–500% saturation using fluorescence lifetime technology, with accuracy of ±1% or ±0.2 mg/L up to 20 mg/L and RS-485 Modbus output. It provides automatic temperature/pressure compensation, salinity compensation, and an integrated self-cleaning brush to reduce maintenance, suitable for water quality monitoring.
- Accuracy
- 0–20 mg/L: ±1% or ±0.2 mg/L; >20 mg/L: ±5% or ±0.6 mg/L
- Measuring range
- 0–50 mg/L or 0–500% saturation
- Output / interface
- RS-485, MODBUS protocol
- Process connection / installation
- NPT3/4 thread, input type installation
- Fluorescence lifetime technology with no oxygen consumption and no H2S interference
- Integrated self-cleaning brush reduces microbial adhesion and maintenance
- Automatic temperature and pressure compensation; manual salinity input compensation
- RS-485 output, Modbus protocol compatible
- Pre-calibrated; supports 1-point or 2-point calibration
