IoT WIRELESS DATA LOGGER FOR 3 CURRENT INPUTS 0-20mA AND TWO-STATE INPUT, WITH BUILT-IN 4G MODEM AND FLAT RATE SIM CARD

IoT Wireless datalogger with built-in GSM modem and Flat Rate SIM Card allows the instant connection to the COMET Cloud.

IoT Datalogger is designed to record 3 current inputs and 1 binary input. 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.
