About the Tzone TT20SI
The Tzone TT20SI is a single-use GPS temperature tracker that records temperature from -30 to +60°C. Tzone specifies the TT20SI at ±0.5°C (-25 to +60°C), ±1.0°C otherwise accuracy with 0.1°C resolution. Down to -30°C, the TT20SI covers 2–8°C fridges as well as -20°C freezers.
Memory holds 16,072 readings with an interval settable from 5 to 60 min (default 15 min), about 167 days of logging at 15-minute steps. The TT20SI sends readings over 4G with location, so alerts arrive while the logger is in place.
