The easy to use Model 9700 is designed with improved sensor input and interface flexibility, including the ability to interface with negative temperature coefficient RTD’s and Chromel® vs. Gold thermocouples. The Model 9700 can display two sensor inputs simultaneously using two high resolution 24-bit analog-to digital converters with a separate current source for each input. Also included as standard equipment is communtication interfaces via a serial RS-232 port and a parallel IEEE-488 bus. The Model 9700 is also equipped with 2 relays and Accu-tune autotuning in the control circuitry. It is backed by Scientific Instruments tradition of excellence in cryogenic sensors and instrumentation.
