IoT WIRELESS FOUR CHANNEL DATA LOGGER WITH PULSE AND TWO-STATE INPUTS, WITH BUILT-IN 4G MODEM

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 from four binary inputs or from pulse and two binary inputs. In case of exceeded set limits, email 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.
