The Extech SD900 is a 3-Channel DC Current Datalogger that lets a technician monitor and record DC mA values from three external sensors, transducers, and other sources using one meter. Alongside each measurement it captures the time and date the reading was taken, and a large triple LCD shows all three DC current channels at once so the full picture of a measurement setup is visible on a single display.
The SD900 is suited to a range of recording and monitoring tasks, including pH recording, 4 to 20mA recording, low-level signal monitoring, photovoltaic studies, and battery studies. It also serves process control, R&D, medical and pharmaceutical work, and environmental studies, making it a flexible logger wherever low-level DC current signals need to be tracked over time.
ValueTronics supplies the SD900 from its own 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold our own inventory rather than sourcing each order on demand.
Extech Instruments operates as part of FLIR Systems, the brand named in this product's copyright line. Its measurement products are issued under the Extech name within the broader FLIR organization.
