Automatic Calibration of ppb Dissolved Oxygen Probe
A typical set – up for automatic calibration in a boiler water sampling system is shown in
Figure 15-10. The solenoid valve and connections should be supplied by others and must
be positively air tight to prevent leakage and erroneous measurements.
The solenoid valve is wired to assigned relay contacts in the UDA2182 analyzer and will
operate at a frequency, and for duration as assigned by the end user.
