Chemistry MultiMeasure Sensor Introduction
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 standalone 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 computer 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

Xplorer GLX Setup
If you are using an Xplorer GLX in standalone mode, press to start 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
Sensors screen (from the Home screen, press ). In the Sensors screen you can
also change the sampling rate and open the calibration dialog box. For more instructions on using the Xplorer GLX, refer to the GLX Users’ Guide.

Temperature
Use this component of the multi-sensor to measure the temperature of a fluid or
object. The measurement can be displayed in units of °C, °F, or K. (In DataStudio,
click the Setup button to change units.) You can use the included stainless steel probe
or a different probe, such as the Fast-response Probe (PS-2135) or Skin/Surface Probe
(PS-2131). PASCO apparatu s containing an embedded 10 kΩ thermistor can also be
connected to the multi-sensor. The multi-sensor automatically detects the presence of
a temperature probe, and it will only collect temperature data if a probe is connected.
Measuring Temperature
To measure temperature, connect the probe and start data collection. Immerse the tip
of the probe in a fluid or place it in contact with an object. The included stainless steel
probe can be used in both dry conditions and in liquids, such as water and other mild
chemicals and solutions.
Tip: For better chemical resistance, use a Teflon® cover (CI-6549).
Temperature Calibration
The temperature measurement can be calibrated; however, for most applications calibration is not necessary. Use a two-point calibration with two standards of known
temperature. For instructions on calibrating in DataStudio, see Appendix A. For
instructions on calibrating on the Xplorer GLX, refer to the Xplorer GLX Users’
Guide.
pH/ISE/ORP
The pH/ISE/ORP input of the multi-sensor is a specialized voltage sensor. Its BNC
connector accepts the included pH electrode, as well as ISE and ORP electrodes. The
sensor measures the voltage produced by any of these electrodes. When used with a
pH probe, the sensor also computes the pH based on the measured voltage.
Connect the pH electrode (or other electrode) to the pH/ISE/ORP port and start data
collection. On your computer or interface, display the ISE V oltage measurement (this
measurement is valid for pH and ORP electrodes as well as ISE) or the pH measurement for the calculated pH (assuming that the pH electrode is connected).
Measuring pH
The pH electrode produces a voltage proportional to the pH of the solution that it is
immersed in. This voltage is measured by the multi-sensor, which computes pH.
