U24-001 Fresh Water Conductivity Data Logger

• Non-contact sensor provides long life and less measurement drift
• Provides easy access to sensor for cleaning and shedding air bubbles
• HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity
• USB optical interface provides high-speed, reliable data offload in wet environments
• Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport

• Memory - 18,500 temperature and conductivity measurements when using one conductivity range; 14,400 sets of measurements when using both conductivity ranges (64kbytes)
• Sample rate - 1 second to 18 hrs, fixed or multiple-rate sampling with up to 8 user-defined sampling intervals
• Battery life - 3 years (@ 1 min logging)
• Maximum Depth - 70 m (225')
• Operating Range - -2 to 36°C (28° to 97°F) - non freezing
• Weight - 193 gm (6.82 ounces), buoyancy in freshwater: -59.8 gm (-2.11 ounces)
• Size - 3.18 cm diameter x 16.5 cm, with 6.3 mm mounting hole (1.25" diameter x 6.5", ¼" hole)
• Calibrated Range - Conductivity: Low Range: 0 to 1,000 µS/cm; Full Range: 0 to 10,000 µS/cm - Temperature: 5 to 35C (41 to 95F)
• Accuracy - Conductivity: 3% of reading, or 5 µS/cm, whichever is greater / Temperature: 0.1C (0.2F)
