Tidbit Mx Temperature 5000′ Data Logger

The HOBO MX2204 TidbiT water 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!

Features: – Convenient wireless setup and download via Bluetooth Low Energy (BLE)- Large memory stores 96,000 measurements- Waterproof to 1500 meters (5000 feet)
– User-replaceable battery- Waterproof boot protects the logger during deployment- LED alarm notifies you when temperature exceeds set threshold- Water detection feature conserves battery life- +- 0.2 C (+- 0.36 F) accuracy

Specifications

Temperature: – Range (in air): -20 to 70 C (-4 to 158 F) – Range (in water): -20 to 50 C (-4 to 122 F) in water, maximum sustained temperature in water 30 C (86 F) – Accuracy: +- 0.25 C from -20 to 0 C (+-.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: <0.1 C (0.18 F) per year- Response: 15 minutes typical to 90% in air moving 1 m/s, unmounted; 4 minutes typical to 90% in stirred water, unmounted Data Logger: – Radio Power: 1 mW (0 dBm)- Transmission Range: Approximately 30.5 m (100 ft) 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- Buoyancy (Fresh Water): 7.6 g (0.27 oz) negative- Waterproof: To 1,524 m (5,000 ft)- Memory: 96,000 measurements- Battery: CR2477 3V lithium, non-replaceable- Time Accuracy: +- 1 minute per month at 25 C (77 F)- Full Memory Dowload: Approximately 45 seconds; may take longer the farther the device is from the logger- Wetted Materials: Epoxy case, Santoprene (TPE) boot- Dimensions: 4.06 x 6.99 x 3.51 cm (1.6 x 2.75 x 1.38 inches) Water detection: – Water conductivity level of 100 ?S/cm or greater necessary for reliable detection of water. Deionized water or water below 100 ?S/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). Battery life: – 3 years, typical at 25?C (77?F) with logging interval of 1 minute and Bluetooth Always Off disabled 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 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.
