Made for wireless data logging, this battery-powered logger records temperature across a single channel from internal sensors. It transfers readings to a phone or tablet over Bluetooth Low Energy. Submersible and waterproof to 1500 m (5000 ft), it works great for underwater and outdoor temperature monitoring.

Submersible and waterproof to 1500 m (5000 ft), it works great for underwater and outdoor temperature monitoring.
The HOBO TidbiT waterproof temperature logger leverages the power of Bluetooth Low Energy (BLE) to deliver high-accuracy temperature measurements straight to your iOS or Android mobile device. Designed for durability, this rugged waterproof logger is ideal for long-term deployments in streams, lakes, and oceans. Data collection in the field has never been easier!
Remotely access your data in Onset's cloud-based HOBOlink software with the new MX Gateway.
Features
Applications
| Accuracy | ±0.25°C from -20° to 0°C (±0.45°F from -4° to 32°F) ±0.2°C from 0° to 70°C (±0.36°F from 32° to 158°F) |
| Resolution | 0.01°C (0.018°F) |
| Drift | less than 0.1°C (0.18°F) per year |
| Radio power | 1 mW (0 dBm) |
| Transmission range | Approximately 30.5 m (100 ') line-of-sight |
| Wireless data standard | Bluetooth Smart (Bluetooth Low Energy, Bluetooth 4.0) |
| Logger operating range | -20° to 70°C (-4° to 158°F) |
| Logging rate | 1 second to 18 hours |
| 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 0°C (32°F). |
| Memory | 96,000 measurements |
| Battery | CR2477 3V lithium, user replaceable in MX2203, non-replaceable in MX2204 |
| Battery life | 3 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always On in software. 5 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off or Bluetooth Off Water Detect in software. |
| Time accuracy | ±1 minute per month at 25°C (77°F) |
| Full memory download | Approximately 45 seconds; may take longer the farther the device is from the logger |
| Environmental rating | IP68 |
| Range | -20° to 70°C (-4° to 158°F) in air; -20° to 50°C (-4° to 122°F) in water, maximum sustained temperature in water 30°C (86°F) |
| Response time | 15 minutes typical to 90% in air moving 1 m/s, unmounted; 4 minutes typical to 90% in stirred water, unmounted |
| Buoyancy (fresh water) | 7.6 g (0.27 oz) negative |
| Waterproof | To 1,524 m (5,000 ') |
| Wetted materials | Epoxy case, Santoprene (TPE) boot |
| Dimensions | 1.6" x 2.75" x 1.38" (4.06 x 6.99 x 3.51 cm) |
| Weight | 1.16 oz (32.8 g) |
