Introduction
The PS-2170 Chemistry MultiMeasure Sensor combines four sensors in a single unit:
• Temperature
• pH, ORP and ion-selective electrode voltage
• Absolute gas pressure
• Voltage
When connected to a PASPORT interface, the multi-sensor collects data at up to 100
samples per second from each component sensor. You can use just one component
sensor at a time or any combination simultaneously. If you have a PASPORT interface
that supports multiple sensors, or if you have more than one interface connected to
your computer, you can use the Chemistry MultiMeasure Sensor in combination with
other PASPORT sensors.
Sensor, Interface, and Software Setup
Connect the multi-sensor to your PASPORT interface as pictured (right).
Connect any or all of the included probes to the multi-sensor. (You can leave
any of the probes disconnected if you do not plan to use it.) If you will be
using an ion-selective electrode or oxygen reduction potential electrode,
connect it to the pH/ISE/ORP port. If you plan to measure pressure in an
apparatus or the included syringe, connect it to the sensor’s pressure port
using the included tubing and a quick-release connector.
Follow the instructions below to set up the sensor with DataStudio software
(if you are using a computer) or the Xplorer GLX (if you are using it stand-
alone without a computer).
For detailed information about each of the multi-sensor sensor’s component
sensors see pages 3–5.
DataStudio Setup
If you are using a computer, connect the PASPORT interface to the com-
puter and start DataStudio. (Refer to the documentation that came with your
PASPORT interface for instructions on connecting it to your computer.) In
DataStudio, click the Start button to begin data collection; click the Stop button to
stop data collection.
Note that the sensor may collected data for probes that are not connected. Hide or
ignore these measurements. To hide measurements that you do not need, open the
Experiment Setup Window by clicking the Setup button. In the Setup window you
can also change the sampling rate and open the calibration dialog box (see Appendix
A). For more instructions on using DataStudio, press F1 to open DataStudio’s on-line
help.
