U3121Msim Internet of Things Wireless Temperature and Relative Humidity Data Logger for External Probe with Built-in 2G Modem and Fixed Fee SIM Card
U3121Msim
The IoT Wireless Data Logger Kit comes with a built-in GSM modem and fixed-fee SIM card for instant connection to COMET Cloud.
The IoT DataCORDER is designed to record temperature and humidity from external sensors. SMS and JSON messages can be sent via GPRS data connection if the email sent exceeds the set limit.
Alarms can also be displayed locally via LEDs, LCDs and the built-in buzzer.
Recording takes place in a non-volatile electronic memory. Data can be transferred to a computer via the included USB-C cable.
The device includes a traceable calibration certificate and declares that the calibrator's metrological traceability is based on the EN ISO/IEC 17025 standard.
Warranty: 3 years
