AK-TO1v5-NBIoT
NB-IoT temperature logger with probe
NB-IoT logger with a 1 m temperature probe: the device stays outside while the probe measures inside the refrigerator, freezer or cold room.
The probe measures inside a freezer or a cold room while the logger stays outside, where the cellular signal is better and the battery works at room temperature.
Specifications
- Measurement: temperature, waterproof external probe, 1 m (other lengths on request).
- Probe range: −55 to +125 °C.
- Accuracy: 0.5 °C between −10 and +85 °C; 2 °C outside that span.
- Resolution: 0.1 °C.
- Measurement interval: from 1 minute to 10 days.
- On-device alarms: upper and lower thresholds with hysteresis; immediate transmission when a reading goes out of range.
- Communication: NB-IoT; data line provided by AKIoT.
- Power: replaceable lithium batteries.
- Protection: logger IP30, for indoor use.
