Advanced Chemistry Sensor Introduction

Introduction
The PS-2172 Advanced Chemistry Sensor combines four sensors in a single unit:
• Temperature
• pH, ORP and ion-selective electrode voltage
• Absolute gas pressure
• Conductivity
When connected to a PASPORT interface, the Advanced Chemistry 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 Advanced Chemistry 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 Capstone,
SPARKvue/SPARK SLS, or the Xplorer GLX (standalone).
For detailed information about each of the multi-sensor sensor’s component
sensors see pages 3–5.
Capstone Setup
Connect the PASPORT interface using a Capstone supported interface.
Build one or more displays for data. Press
to start data collection and
to stop data collection.
Note that the sensor will collect data for probes that are not connected. These data are
listed in the Data Summary and are displayed if selected on one or more displays. The
default sampling rate and other parameters are defined with Hardware Setup in the
Tool Palette. Calibration is performed with the Calibration wizard in the Tool Palette.
For more instructions on using Capstone, refer to the Capstone Online Help or User’s
Guide.
SPARKvue/SPARK SLS Setup
Connect the PASPORT interface directly to a SPARK SLS or to a computer using a
SPARKvue supported interface. Build one or more displays for data. Press
to
start data collection and to stop data collection.
The default sampling rate is defined with Sampling Options. Calibration is performed
with Experiment Tools > Calibrate Sensor. For more instructions on using the
