Temperature and humidity data logger with built-in sensors
Datalogger is designed to record temperature and humidity.
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.
