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 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

Resolution: < 0.02 kPa (0.003 psi), 0.21 cm (0.007 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 (10-bit):

0.1°C at 20°C

0.18°F at 68°F

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

Memory (non-volatile): 64K bytes memory (approx. 21,700 pressure and temperature samples)

Dimensions: 2.46 cm (0.97 inches) diameter, 15 cm (5.9 inches) length; mounting hole 6.3 mm (0.25 inches) diameter

Weight: Approximately 210 g (7.4 oz)

Wetted materials: 316 stainless steel, Viton® o-rings, acetyl cap, ceramic sensor

Shock/drop:

Logger is sensitive to shocks. Handle with care and avoid any impact. Always use proper packaging when shipping the logger.

Logging interval:

Fixed-rate or multiple logging intervals, with up to 8 user-defined logging intervals and durations; logging intervals from 1 second to 18 hours. Refer to HOBOware software manual.

Launch modes: Immediate start and delayed start

Offload modes: Offload while logging; stop and offload

Battery indication: Battery voltage can be viewed in status screen and optionally logged in datafile. Low battery indication in datafile.

Environmental Rating: IP68
