Model LXT-220 Dissolved Oxygen Controller is a
robust and versatile instrument for the measurement and process control
of dissolved oxygen in a liquid component. Highly customizable, the
Model LXT-220 comes standard with a single 4-20mA current output
but can have as many as five. The current output is field selectable and
may be expanded to any range within the transmitter’s full operating
range. It can also be programmed as reverse acting; for example, a 4-20
mA output for a range of 0 to 10 ppm can be reversed to 10 to 0 ppm.
