Specifications
Water level sensor specifications
- Operation Range: 0 to 207 kPa (0 to 30 psia); approximately 0 to 9 m (0 to 30 ft) of water depth at sea level, or 0 to 12 m (0 to 40 ft) of water at 3,000 m (10,000 ft) of altitude
- Factory Calibrated Range: 69 to 207 kPa (10 to 30 psia), 0 to 40 C (32 to 104 F)
- Burst Pressure: 310 kPa (45 psia) or 18 m (60 ft) depth
- Water Level Accuracy: Typical error: +/- 0.05% FS, 0.5 cm (0.015 ft) water; Maximum error: +/- 0.1% FS, 1.0 cm (0.03 ft) water
- Raw Pressure Accuracy: +/- 0.3% FS, 0.62 kPa (0.09 psi) maximum error
Data logger specifications
- Smart Sensor Connectors: 5
- Smart Sensor Network Cable Length: 100 m (328 ft) maximum
- Smart Sensor Data Channels: Maximum of 15 (some smart sensors use more than one data channel; see sensor manual for details)
- Logging Rate: 1 minute to 18 hours
- Time Accuracy: +/- 8 seconds per month in 0 to 40 C (32 to 104 F) range; +/- 30 seconds per month in -40 to 60 C (-40 to 140 F) range
- Battery Type/Power Source: Integrated 1.7 watt solar panel and NiMH rechargeable battery pack; optional AC power adapter (P-AC-1) or external solar panel (SOLAR-xW) can be used in place of integrated solar panel

- Weight: 678 g (23.9 oz)
Battery life specifications
Typical 3 to 5 years when operated in the temperature range -20 to 40 C (-4 to 104 F); operation outside this range will reduce the battery service life.
Maximum connection rates with built-in solar panel, in full sun:
- 10 minute connections year round for latitudes less than +/- 40 degrees
- 10 minute connections through three seasons in other regions, reduced to 30 minute connections in winter
Maximum connection rates with external 5W or 15W solar panels:
- 10 minute connections year round, in full sun
- Connection rate with external solar panels may be less if deployed in partial sun
Battery life without solar recharging, with hourly connections and 1 minute logging: 2 months
