| Absolute Pressure | Measurement Range: 0 to 400 kPa (0 to 58 psia) Factory Calibrated Range: 69 to 400 kPa (10 to 58 psia) @ 0°C to 40°C (32°F to 104°F) Burst Pressure: 500 kPa (72.5 psia) or 40.8 Meters (134 ft) Depth Raw Pressure Accuracy*: Maximum Error - ±0.3% FS, 1.2 kPa (0.17 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 30.6 Meters (0 to 100 ft) of Water Depth at Sea Level or 0 to 33.6 Meters (0 to 111 ft) of Water at 3,000 Meters (10,000 ft) of Altitude Accuracy*: Typical - ±0.05% FS, 1.5 cm (0.05 ft) Water; Maximum - ±0.1% FS, 3.0 cm (0.1 ft) Water Resolution: <0.04 kPa (0.006 psi), 0.41 cm (0.013 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 |
