IoT Wireless CO2 datalogger with built-in sensor, 4G modem

GSM datalogger is designed to record CO2 from built-in sensor. In case of exceeded set limits, SMS and JSON messages can be sent via GPRS data connection. Measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarm and analysis system.

It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. 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.

Possibility to extend the measuring range for an additional charge:

Measuring range: 0 to 10 000 ppm
Accuracy: 100 ppm + 5% of the measured value at 25 °C and 1013 hPa
