About the Tzone TT18-4G-M
The Tzone TT18-4G-M is a reusable GPS temperature tracker that records temperature and relative humidity from -30 to +60°C. Tzone specifies the TT18-4G-M at ±0.3°C accuracy with 0.1°C resolution. Down to -30°C, the TT18-4G-M covers 2–8°C fridges as well as -20°C freezers.
Memory holds 18,000 readings at a 30 min interval, about 375 days of logging at 30-minute steps. The TT18-4G-M sends readings over 2G/NB-IoT/CAT-M with location, so alerts arrive while the logger is in place.
Physically, the TT18-4G-M has IP54 protection. In practice the Tzone TT18-4G-M fits shipments that need live location and alerts, 2–8°C or frozen.
