Data logger for 3 current inputs 0-20mA and 1 two-state input

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.

Included in delivery:

  • code
    U6841
  • Warranty
    3 years
