HOBO by Onset U24-002-C - Conductivity Data Logger Specs
| Brand | Kestrel |
| Measurements | Actual Conductivity, Temperature, Specific Conductance at 25C (calculated), Salinity (calculated using PSS-78, the Practical Salinity Scale 1978) |
| Conductivity Measurement Range | (Calibrated Range) |
| High Range | 5000 to 55,000 uS/cm |
| Low Range | 100 to 10,000 uS/cm Over the range of 5 to 35C (41 to 95F) |
| Temperature Measurement Range | 5 to 35C (41 to 95F) |
| Specific Conductance Accuracy | (in Calibrated Range using Conductivity Assistant and Calibration Measurements) |
| Low Range | 3% of reading or 50 µS/cm, whichever is greater |
| High Range | 5% of reading, in waters within a range of ±3,000 µS/cm; waters with greater variation can have substantially greater error (see Plot C) |
| Conductivity | 2 uS/cm |
| Temperature | 0.01°C (typical 0.02°F) |
| Conductivity Drift | Up to 12% sensor drift per month, exclusive of drift from fouling. Monthly start- and end-point calibration should be used with the HOBOware Conductivity Assistant to achieve the specified Specific Conductance accuracy |
| Response time | 1 second to 90% of change (in water) |
| Operating Range | -2 to 36C (28 to 97F) – non-freezing |
| 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 |
| Clock accuracy | +/- 1 minute per month |
| Battery life | 3 years (@ 1 min logging) |
| Maximum Depth | 70 m (225') |
| 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) |
| Wetted Housing Materials | Delrin housing, epoxy, stainless steel retaining ring, polypropylene, Buna rubber O-ring, titanium pentoxide (inert coating over sensor) – all materials are suitable for long-term use in saltwater. |
| CE Compliance | The CE Marking identifies this product as complying with all relevant directives in the European Union (EU) |
