Onset HOBO W-CTD Conductivity Temperature and Depth Water Sensor Specifications
| Conductivity | Measurement Range (Electrical Conductivity and Specific Conductance): 0 to 100,000 µS/cm Measurement Range (Salinity using PSS-78): 2 to 42 PSU Measurement Range (Total Dissolved Solids): 0 to 100,000 mg/L Calibrated Range (Electrical Conductivity): 50 to 80,000 µS/cm @ 5°C to 35°C (41°F to 95°F) Accuracy (Conductivity): ±2% or 15 µS/cm Whichever is Greater Accuracy (Salinity): ±2% of Reading or 0.1 PSU, Whichever is Greater Resolution (Conductivity): 0.1 µS/cm from 0 to 1,000 µS/cm; 1 µS/cm from 1,000 to 10,000 µS/cm; 10 µS/cm from 10,000 to 100,000 µS/cm Resolution (Salinity): 0.01 PSU Resolution (Total Dissolved Solids): 0.1 mg/L Response Time: 1 second to 90% at a Stable Temperature |
| Absolute Pressure | Measurement Range: 0 to 850 kPa (0 to 123.3 psia) Factory Calibrated Range: 69 to 850 kPa (10 to 123.3 psia) @ 0°C to 40°C (32°F to 104°F) Burst Pressure: 1200 kPa (174 psia) or 112 Meters (368 ft) Depth Raw Pressure Accuracy*: Maximum Error - ±0.3% FS, 2.55 kPa (0.37 psi) Pressure Response Time**: <1 Second to 90% at a Stable Temperature * Raw Pressure Accuracy: Absolute Pressure Sensor Accuracy includes All Sensor Drift, Temperature and Hysteresis-Induced Errors. ** Changes in Temperature: Allow 20 Minutes in Water to Achieve Full Temperature Compensation of the Pressure Sensor. There can be up to 0.5% of Additional Error due to Rapid Temperature Changes. |
| Water Level | Measurement Range: 0 to 76.5 Meters (0 to 251 ft) of Water Depth at Sea Level or 0 to 79.5 Meters (0 to 262 ft) of Water at 3,000 Meters (10,000 ft) of Altitude Accuracy*: Typical - ±0.05% FS, 3.8 cm (0.125 ft) Water; Maximum - ±0.1% FS, 7.6 cm (0.25 ft) Water Resolution: <0.085 kPa (0.012 psi), 0.87 cm (0.028 ft) Water * Water Level Accuracy: With Accurate Reference Water Level Measurement, Known Water Density, and a Stable Temperature Environment. System Water Level Accuracy Equals the Sum of the Barometric Water Level Accuracy Plus the Selected CTD Sensor Water Level Accuracy. |
| Temperature | Measurement Range: -20°C to 50°C (-40°F to 122°F), Non-Freezing Water Accuracy: ±0.15°C (±0.27°F) from 0°C to 50°C (32°F to 122°F) Resolution: 0.01°C at 25°C (0.018°F at 77°F) Response Time: 3 minutes to 90% in Water (Typical) Drift: <0.1°C (0.18°F) per Year |
