The Comet U0122 datalogger is designed to record 2 temperatures, one using an internal sensor and one using an externally connectable Pt1000 temperature sensor. The recording is made to a non-volatile electronic memory. Data can be transferred to a personal computer at any time via USB-C interface. The logger allows to work with alarms ofmeasured values and to indicate them locally on the device by LED, LCD and acoustically.
The device includes a calibration sheet with declared metrological continuity of standards, which is based on the requirements of EN ISO/IEC 17025.
