Description
This logger is designed for recording and storing temperature, humidity, atmospheric pressure, and CO2 values. In case of exceeding the set limit values, the device can issue an alarm signal through a sound signal, light indication, and display of the exceedance data on the screen.
Data is recorded in non-volatile electronic memory. Data can be transferred to a PC via USB-C.
The recorder is supplied with a calibration certificate from the manufacturer with declared metrological accuracy relative to standards, based on the requirements of the European standard EN ISO / IEC 17025.
