    IoT Wireless Temperature and Relative Humidity Datalogger, with built-in 2G modem and Flat Rate SIM Card
IoT Wireless Datalogger kit with built-in GSM modem and Flat Rate SIM Card allows the instant connection to the COMET Cloud.
IoT Datalogger is designed to record temperature and humidity from built-in sensors. In case of exceeded set limits e-mail is sent from the COMET Cloud.
Alarms are also indicated locally by LED, LCD and acoustically by built-in beeper.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable.
GSM recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
