HD31 – Handheld Portable Multifunction Data Logger
Brand: Delta OHM S.R.L.
HD31 is a portable multifunctional data logger instrument with color graphic LCD display.
It is equipped with 3 independent inputs and each input can be connected to SICRAM probes for the measurement of a large variety of physical quantities.
The SICRAM module allows the instrument to immediately recognize the type of probe connected.
Moreover, it stores into memory the probe calibration data: in this way the probe can be indirectly connected to the three inputs of the instrument or to another instrument with no need to be recalibrated.
All probes are supplied factory-calibrated and are interchangeable.
The instrument’s inputs can also be connected to non SICRAM probes, by using the relevant interface modules between instrument and probe.
Measurement units are selectable according to the measured physical quantity.
The display can show up to 36 quantities, three of which can be displayed simultaneously in numeric format.
A real-time measured quantity graph is also shown in the display.
Data logging function with data storing in CSV format directly to the SD type memory card, for a long duration of the logging.
Storage interval configurable by the user.
USB port with mini-USB connector for PC connection, for configuration and download of the acquired data.
Automatic or manual start and stop of the logging.
Storing of date and time of each recorded sample.
Automatic creation of measurement reports in PDF format on the memory card.
