This tiny completely sealed underwater temperature data logger utilizes optic communications for launch and readout. This model records 32K of temperature measurements from -5°C to 37°C (24 °F to 99°F). Waterproof to 333m (1000ft), StowAway TidbiT units should not be used in wet (>90% RH) environments and water temperatures higher than +30°C for more than eight weeks cumulatively.
Features:
Waterproof to 1000 feet
Completely sealed in epoxy; very durable
User-selectable sampling interval: 0.5 seconds to 9 hours, recording times up to several years
Blinking LED light shows if temperature goes out of user-determined limits
Precision components eliminate the need for user calibration
Programmable start time/date
Triggered start with coupler or magnet
Memory modes stop when full or wrap-around when full
Nonvolatile EEPROM memory retains data even if battery fails
Multiple sampling with minimum, maximum or averaging
Blinking LED light confirms operation

Specified range is narrower than nominal range due to precision calibration process. Using TidbiT Temp loggers in wet environments (>90% RH) over 86°F (30°C) for extended periods of more than 8 weeks cumulative may lead to premature failure. For applications over 30°C use the HOBO® Water Temp Pro v2.
