Transmission Range Approximately 30.5 m (100 ft) line-of-sight
Wireless Data Standard Bluetooth Low Energy (Bluetooth Smart)
Logging Rate 1 second to 18 hours
Logging Modes Fixed interval, multiple intervals with up to 8 user-defined logging intervals and durations, or event-triggered burst
Memory Modes Wrap when full or stop when full
Start Modes Immediate, date & time, or next interval
Stop Modes When memory full, stop with HOBOmobile, date & time, or after a set logging period
Time Accuracy ±1 minute per month 0° to 50°C (32° to 122°F)
Battery Two AA, 1.5 V alkaline batteries, user replaceable
Battery Life 1 year, typical with logging interval of 1 minute. Faster logging and/or statistics sampling intervals, entering burst logging mode, excessive readouts, checking of Full Status Details, and remaining connected with HOBOmobile will impact battery life.
Memory 256 KB memory (30,000 sets of measurements)
Full Memory Download Time Approximately 2 minutes; may take longer the further the device is from the top end of the logger
