Data logger for 3 current inputs 0-20mA and 1 two-state inputcode: U6841
Datalogger is designed to record 3 current inputs and 1 binary input.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via USB-C.
In case of exceeded set limits alarms are indicated by LED, LCD and acoustically by built-in beeper.
Recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
