Dissolved Oxygen Quick Start
The PS-2108 Dissolved Oxygen Sensor measures the amount of
dissolved oxygen in a solution in milligrams per liter.
A d d it i o n al Eq u ip m e n t N e e d e d
•
PASPORT Link Device (USB Link, Xplorer, etc.)
•
EZscreen or DataStudio
Eq u ip m e n t S e t up
1. Connect the PASPORT Link Device to a USB port on your computer or USB hub.
2. Connect the Dissolved Oxygen probe to the sensor.
3. Connect the sensor to the PASPORT Link Device.
4. The software launches when it detects a PASPORT sensor. From the
PASPORTAL screen, select a point of entry:
• an activity in the Workbook window,
• EZscreen, or
• DataStudio.

Note: Prior to first use, fill the
electrode membrane cartridge and
housing with a filling solution. Refer
to the Maintenance card included
with the sensor.
