The DOCN-72 is an easy-to-use dissolved<br />
oxygen analyzer/controller designed for use<br />
with the DOE-72 submersible mounted<br />
membrane dissolved oxygen sensor.<br />
The sensor features a replaceable<br />
cartridge, simplifying the task of installing<br />
a new membrane.<br />
Besides viewing measured dissolved oxygen<br />
n ppm or % saturation, you can display<br />
other important system information (analog<br />
output values, process temperature, next<br />
scheduled date of calibration, etc.) by using<br />
the or key to scroll the lower line on the<br />
measurement screen. The analyzer<br />
provides two sets of analog outputs,<br />
each consisting of one 4 to 20 mA and one<br />
0 to 5 Vdc/0 to 1 mA output. Each output<br />
set can be assigned to represent the<br />
measured D.O. (in ppm or % saturation) or<br />
temperature. Also, whenever the analyzer<br />
detects that one of the 4 to 20 mA loops<br />
is open, it displays a “Current Load High”<br />
diagnostic message.<br />
The analyzer logbook records up to 100<br />
system events, including calibrations,<br />
warning and failure messages, powerup/power-down,<br />
and configuration activity.<br />
Each event is logged with the date and time<br />
of occurrence.<br />
