The ER180C has two analog input channels, and has analog and digital outputs. The ER181C has one analog input channel and has no analog/digital outputs.
Unlike many specialist data acquisition systems, they can be used to collect data from completely different types of sources on different channels (e.g. pH, oxygen concentration, and temperature) because channel sensitivity and filtering is independently adjustable.
Replace your chart recorder, XY plotter, or oscilloscope (to 1000 Hz), with these systems to get the benefits of the latest generation of computer technology in your laboratory.
