Applications
| Temperature Sensor | |
| Range | -4 to 158°F (-20 to 70°C) in air -4 to 122°F (-20 to 50°C) in water |
| Accuracy | ±.45°F from -4 to 32°F (±0.25°C from -20 to 0°C) ±0.36°F from 32 to 158°F (±0.2°C from 0 to 70°C) |
| Resolution | 0.018°F (0.01°C) |
| Drift | <0.18°F (0.1°C) per year |
| Response Time | 17 minutes typical to 90% in air moving 1 m/s, unmounted 7 minutes typical to 90% in stirred water, unmounted |
| Logger | |
| Operating Range | -4 to 158°F (-20 to 70°C) in air |
| Buoyancy (Fresh Water) | 0.11 oz (3.1 g) negative |
| Waterproof | To 400' (122 m) |
| Water Detection | Water conductivity level of 100 μS/cm or greater necessary for reliable detection of water. Deionized water or water below 100 μS/cm may not be detected. The water conductivity circuit may not reliably detect water that has frozen around the electrodes, i.e. below 32°F (0°C) |
| Radio Power | 1 mW (0 dBm) |
| Transmission Range | Approximately 100' (30.5 m) line-of-sight |
| Wireless Data Standard | Bluetooth Low Energy (Bluetooth Smart) |
| Logging Rate | 1 second to 18 hours |
| Time Accuracy | ±1 minute per month at 77°F (25°C) |
| Battery | Type: CR2477 3 V lithium, user replaceable Life: 3 years, typical at 77°F (25°C) with logging interval of 1 minute and Bluetooth Always Off disabled in software 5 years, typical at 77°F (25°C) with logging interval of 1 minute and Bluetooth Always Off or Bluetooth Off Water Detect enabled in software. Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life |
| Memory | 96,000 measurements |
| Full Memory Download | Approximately 45 seconds; may take longer the farther the device is from the logger |
| Wetted Materials | Polypropylene case, EPDM O-ring, stainless steel screws, Santoprene® (TPE) boot |
| Environmental Rating | IP68 |
| Dimensions | 1.75 x 2.88 x 1.41" (4.45 x 7.32 x 3.58 cm) |
| Weight | 1.28 oz (36.2 g) |
