Description

Features

Lightning protection; no long signal wires, and electronics are shielded in stainless-steel housing
HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature, and water density
Multiple-rate sampling allows faster sampling at critical times such as when pumping starts or stops.
Available in four depth ranges
Ideal for use in wells, streams, lakes, wetlands, and tidal areas
No-vent-tube design for easy reliable deployment
Durable ceramic pressure sensor

Specifications

Pressure Sensor
Operation range: 0 to 145 kPa (0 to 21 psia); approximately 0 to 4 m (0 to 13 ft) of water depth at sea level, or 0 to 7 m (0 to 23 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range: 69 to 145 kPa (10 to 21 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 – 0.075% FS, 0.3 cm (0.01 ft) water
Maximum error: – 0.15% FS, 0.6 cm (0.02 ft) water
Raw pressure accuracy:** 0.3% FS, 0.43 kPa (0.063 psi) maximum error
Resolution: < 0.014 kPa (0.002 psi), 0.14 cm (0.005 ft) water
Pressure response time 90%: < 1 second
Thermal response time (90%): † Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor

Temperature Sensor
Operation range: -20° to 50°C (-4° to 122°F)
Accuracy: 0.37°C at 20°C (0.67°F at 68°F)
Resolution: 0.1°C at 20°C (0.18°F at 68°F) (10-bit)
Response time (90%): 3.5 minutes in water (typical)
Stability (drift): 0.1°C (0.18°F) per year

Logger
Real-time clock: ± 1 minute per month 0° to 50°C (32° to 122°F)
Battery: 2/3 AA, 3.6 Volt Lithium, factory-replaceable
Battery life (typical use): 5 years with 1 minute or greater logging interval
