COMET SYSTEM, s.r.o
4G Wireless Temperature and Relative Humidity Datalogger with flood detector
he U3832G datalogger is used to measure temperature, relative humidity and dew point temperature using internal sensors, plus an attached LD-81 flood detector to indicate water flooding. In case of exceeded set limits, SMS and JSON messages can be sent via 4G 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.
