Introduction
The PS-2170 Chemistry MultiMeasure Sensor combines four sensors in a single unit:
• Temperature • Absolute gas pressure (built-in)
• pH, ORP, and ion-selective electrode voltage • Voltage
The sensor includes a temperature probe, a voltage probe, and a pH electrode. The pressure sensing element does not use an
external probe. The sensor comes with alligator clips and insulators, a syringe, blue polyurethane tubing, and a Hose and Coupling Kit.
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 a pH Electrode (included)
or an ion-selective electrode or oxygen reduction potential electrode, connect it to the
pH/ISE/ORP port (BNC port). Align the grooves of the BNC connector on the probe
with the pins on the BNC port. Push the connector onto the port and turn the connector
clockwise until it locks in place. If you plan to measure pressure in an apparatus or the
included syringe, connect it to the sensor’s pressure port using the included clear tubing and a quick-release connector.
For detailed information about each of the multi-sensor sensor’s component sensors
see pages 4–6.
Follow the instructions in the Computer Setup section to set up the sensor with a
PASPORT-compatible interface connected to a computer using PASCO Capstone or
SPARKvue HD software.
Follow the instructions in the Wireless Setup section to set up the sensor with a mobile
device such as a tablet or smart phone using a wireless interface such as the AirLink2
or SPARKlink and the SPARKvue HD software
Follow the instructions in the Hand-Held Setup section to set up the sensor with a SPARK Science Learning System (SPARK
SLS) or the Xplorer GLX hand-held data-logger.

Computer Setup
Using PASCO Capstone
• Connect a PASPORT-compatible interface to the computer and start the PASCO Capstone software.
(Refer to the documentation that came with your PASPORT interface for instructions on connecting
it to your computer.) In Capstone, click the Record button to begin data collection; click the Stop
button to stop data collection.
• Note that the sensor may collect data for probes that are not
connected. To hide measurements that you do not need,
click the Data Summary icon ( ) in the Tools palette to
open the Sensor Data Summary panel. Click the Visibility
icon ( ) to view the menu of parameters. Check or
un-check the measurements as needed. Click the Data Summary icon again to close the panel.
• In the Workbook page, click one of the configured display
combinations, or drag icons from the Displays palette into the Workbook page. In a display,
click the “<Select Measurement>” menu to view the sensor parameter choices. Click a parameter in the menu to set the measurement for that display.
Using SPARKvue HD
• Connect a PASPORT-compatible interface to the computer and start the
SPARKvue HD software. (Refer to the documentation that came with your
PASPORT interface for instructions on connecting it to your computer.) In
SPARKvue HD, the opening screen shows the list of measurements for the sensor. For example, click “Temperature” and then click “Show” to open a Graph
display screen.
• In the Graph display screen, click the green Record button ( ) to begin recording data. Click the red Stop button ( ) to stop recording data.
Wireless Setup
Using SPARKvue HD
• Use the SPARKvue HD software to pair a mobile device such as a tablet or
smart phone to a PASCO wireless interface such as the AirLink2 or SPARKlink
Air. (Refer to the documentation that came with your PASCO wireless interface
for instructions on connecting it to your mobile device.)
• Connect the sensor to the wireless interface. In SPARKvue HD, the opening
screen shows the list of measurements for the sensor. For example, touch
“Temperature” and then touch “Show” to open a Graph display screen.
• In the Graph display screen, touch the green Record button ( ) to begin
recording data. Touch the red Stop button ( ) to stop recording data.

Chemistry MultiMeasure Sensor Temperature
Hand-held Setup
Using the SPARK SLS
• Connect the sensor to a port on the SPARK SLS and turn on the interface. The sensor parameter screen opens and shows
the list of measurements for the sensor.
• In the sensor parameter screen, touch or click the measurement, and then touch ‘Show’ to open a graph display of the
measurement.
• Touch “Start”( ) to begin recording data. Touch “Stop” ( ) to stop recording data.
Using the Xplorer GLX
• Turn on the interface and connect the sensor to a port on the top. A Digits display of Absolute Pressure (kPa) and Voltage
(V) opens automatically and shows the data being monitored.
• Press the Start/Stop key (s) to begin recording data. Press the same key again to stop recording.
• Note that the sensor may collect 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 (I). In the Sensors
screen, use the up or down cursor keys to highlight a measurement. Press
“Check” (c) to change the visibility of that measurement. (You can also
change the sampling rate and open the calibration dialog box from the Sensors screen.)
Calibration Information
See the Appendices for detailed information about calibrating the sensor.
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. You can use the included stainless steel probe or a different probe, such as the Fast-response Temperature
Probe (PS-2135) or Skin/Surface Temperature Probe (PS-2131). PASCO apparatus containing an embedded 10 k 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 stainless steel probe can be used in both dry conditions and in liquids, such as water and other mild
chemicals and solutions*. The included blue polyurethane tubing allows the stainless steel probe to fit inside a standard 0.25”
diameter stopper hole.
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 the sensor, see the Appendices.
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 ion selective electrodes (ISE) and oxygen reduction potential (ORP) electrodes. The sensor measures the voltage produced by any of these electrodes. When used with a pH electrode, the sensor also computes the pH based on the
measured voltage.
