U4440G

U4440G IoT Wireless Temperature, Relative Humidity, CO2 and atmospheric pressure Datalogger with built-in 4G modem

The GSM data logger is designed to record temperature, humidity, atmospheric pressure and CO2. In case of exceeding the set limits, SMS and JSON messages can be sent via a 4G data connection. The measured values ​​can be sent to the COMET Cloud Internet storage, which is a complete monitoring, alarm and analysis system.

It is also possible to set up regular sending of JSON messages to the COMET database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD and acoustically by a built-in buzzer.
Recording takes place on non-volatile electronic memory. Data can be transferred to a PC via the included USB-C cable.

The GSM logger comes with a traceable calibration certificate with declared metrological traceability of the etalons based on the requirements of EN ISO/IEC 17025.
