Cooper Instruments DFR-1250 Specifications

DFR 1250 - PAPERLESS RECORDER

he DFR 1250 is a feature-rich digital recording system offering
two universally configurable isolated inputs for measuring DC

T

voltage, DC current, thermocouples, and RTDs. It also offers
frequency and pulse inputs, and can be used to measure RPMs with the
correct speed measurement sensor. Combining small package size
with extreme flexibility make the DFR 1250 a powerful, yet
economical, digital data recording system. A maximum sample storage
rate of 100 samples per channel can be set for both channels, allowing
capture of short-duration signal anomalies. The optional DFR 1250
Navigator software offers many convenient and intuitive features to
make reviewing, printing and exporting data easy. Optional USB or
Ethernet ports available for easy data download, or network
connectivity. It has a highly readable LED display, with backlighting
displays real time date or trends. The flexible power supply can use the
included AC adaptor, or input power (12-14 VDC) from another
instrument or battery supply. (Optional rechargeable NIMH battery
pack available.) Time clock and internal RAM have battery back-up to
secure data.
