The SER1CH-UA is a data acquisition system providing 24 bit A/D conversion for one analog input channel at a 1Hz sampling rate. The SER1CH-UA communicates its acquired data to the computer via a standard RS232 serial port. With a very low power consumption of 600 microamps at 9 volts while converting, it is suitable for many field applications. A buffered copy of the A/D reference is available as excitation for ratiometric measurements which are free from TC temperature drift. Three models are available. Application software with source is also included for free.
