Multi-Function Data Logger / HD31
Multi-channel measuring instrument with logger function, large LCD
A probe with SICRAM (a module for storing calibration data) can be connected to the 3-channel input section. We have prepared SICRAM probes that can measure the following elements, and the main unit can automatically recognize the type of sensor connected to the input section. - Temperature - Relative humidity - Atmospheric pressure, differential pressure - Wind speed - Illuminance, radiant illuminance - Carbon dioxide (CO₂) - DC voltage, DC current It is also possible to connect probes without SICRAM using a dedicated interface module. ■ Main Features - 3-channel input - Automatic probe recognition - Color display - Graphical display of measurement values - Configurable measurement units - Automatic logging start/stop - Long-term log data storage on SD card - Automatic PDF report generation - HOLD (hold), REL (relative measurement), DIFF (difference measurement between two inputs of the same element) functions - Detection of maximum, minimum, and average values - Calibration protection with password - USB connection to PC - Serial output to printer - Rechargeable battery - Auto power-off function
