Use this datalogger alongside voltage sensors, transducers and other sources to constantly measure and log DC mV values over a period of time.
With the Extech SD910, voltage levels on pH sensors, current probes, low level signal monitoring equipment, photovoltaic installations, batteries, process equipment and much more can be assessed for irregular voltage activities.
The logger features 3 input channels as standard. All three channels can be read and displayed simultaneously, with all parameters automatically stored on the included SD card alongside a time and date stamp. The readings are stored directly in a CSV file format compatible with Microsoft Excel, making porting to PC as simple as possible.
The rate at which the logger stores information can also be completely adjusted by the user; choose between 2, 5, 10, 30, 60, 120, 300 or 600 seconds, or set the logger to Auto mode.
