U3631G wireless data logger for temperature and relative humidity with connection for a second temperature probe, with built-in 4G COMET modem

Description

The U3631G wireless data logger for temperature and relative humidity with connector for a second temperature probe, with built-in 4G modem COMET is designed to log temperature and humidity from built-in sensors and an external temperature probe.

In case the set limits are exceeded, SMS and JSON messages can be sent over the 4G data connection.

Measured values can be sent to the COMET Cloud, a comprehensive 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 configurable.

Alarms can be displayed locally with LED, LCD and acoustically with built-in beep.

Recording takes place in non-volatile electronic memory. Data can be transferred to a PC via the included USB-C cable.

The inputs of the GSM data logger can be configured for four binary inputs or two binary inputs and two pulse counters.

The GSM recorder includes a traceable calibration certificate with declared metrological traceability of standards based on the requirements of EN ISO/IEC 17025.
