Introduction
The PS-2125 Temperature Sensor measures temperature in
degrees fahrenheit (°F) or celsius (°C), or in kelvin (K). The
included Stainless Steel Temperature Probe has a wide
range, and the included tubing allows the probe to fit inside a
standard 0.25” diameter stopper hole.
The sensor is designed to work with a PASPORT -compatible
interface (such as the UI-5100 850 Universal Interface) and
PASCO data acquisition software (such as PASCO Capstone
or SPARKvue) to measure temperature.
Optional Temperature Probes
The sensor can also be used with other temperature probes.
(See the PASCO catalog or visit www.paseo.com for more
information.).
Other Temperature Probes
Fast Response Temperature Probe PS-2135
Skin/Surface Temperature Probe PS-2131
The Fast Response T emperature Probe has a smaller size and
thermal mass and a range from -30 to 105 °C. The Skin/Surface Temperature Probe has a range from -10 to 70 °C.
Sensor Usage
• Do not place the sensor box or the cable of the probe in
liquids.
• Do not place the probe in a flame or on a hot plate.
• Do not use the probe in liquids other than water or
mildly acidic solutions*.
(*Put a Teflon Sensor Cover - available separately - on the
probe if you plan to use it with strong acids, etc. The cover
has a Chemical Resistance Classification of “E” (acetaldehyde to zinc stearate.))

Setup the Sensor
• Plug the sensor into a PASPORT input port of a PASCO
PASPORT-compatible interface.
NOTE: If more distance is needed between the sensor and
the interface, plug the sensor into a Sensor Extension Cable
(PS-2500), and then plug the cable into the interface.
• Connect the temperature probe to the sensor box.
• Start the PASCO data acquisition software. Set up a data
display in the software.
Using PASCO Capstone Software
• Click the “Hardware Setup” icon in the Tools palette to
open the “Hardware Setup” panel. Confirm that the
Temperature Sensor icon appears with the interface’s
icon.
• In the sensor parameter screen, touch a measurement to
highlight it, and then touch ‘Show’ to open a graph display.
Using Xplorer GLX Datalogger
• When you connect the sensor to the Xplorer GLX Datalogger, a Graph display of temperature versus time automatically opens.
• Click the “Data Summary” icon in the Tools palette to
open the “Data Summary” panel.
• Click the “Properties” icon (that looks like a small gear)
in the “Data Summary” panel to see the “Properties”
panel. Click “Names and Symbols” to change the
default unit from degrees celsius.
• Click one of the display templates in the Capstone workbook page, or double-click an icon in the “Displays”
palette to select a specific data display.
Using SPARKvue Software
• Connect the sensor to a SP ARK Science device and start
the software. In SP ARKvue, the sens or parameter screen
opens and shows the list of measurements for the sensor.
Record Data
• Click “Record”, touch ‘Start’, or press the ‘Record’ button to begin recording data.
Calibrating the Sensor
The Temperature Sensor is factory calibrated, but it can be
calibrated using the following: ice water, hot water, thermometer.
Using PASCO Capstone Software
• Click the “Calibration” icon in the Tools palette to open
the “Calibration” panel. For step 1, confirm that “Temperature” is selected and click “Next”.
• For step 2, confirm that the selected probe is “Temperature Measurement” and click “Next”.
• For step 3, confirm that “Two Standards” is the type of
calibration, and click “Next”.
• For step 4, put the probe and the thermometer in ice
water. When the temperature on the thermometer is at or
close to 0 °C, enter the thermometer reading in the
“Standard Value” text box. Click “Set Current Value to
Standard Value” and click “Next”.

Model No.PS-2125 Specifications
• For step 5, put the probe and thermometer into hot water
(boiling hot, if available). When the thermometer
reaches its highest point, enter the thermometer reading
in the “Standard Value” text box. Click “Set Current
Value to Standard Value” and click “Next”.
• In the final step, review your calibration and click “Finish”.
Using SPARKvue Software
After SPARKvue starts, the Sensor Parameter screen shows
the measurements that the sensor can make.
• Touch “Temperature” and then touch “Show” to open a
page with a graph display.
• In the graph page, touch the “SPARKvue Help” icon
( ) to open the SP ARKvue User’ s Guide page.
• Touch “Setting up an experiment” and then touch “Calibrating sensors”.
• Touch “Performing a calibration” and then touch “Performing a 2-point calibration”.
• Put the probe and the thermometer in ice water. Follow
the instructions in the SPARKvue Help page about “Calibration Point 1”. (Use the keypad window that opens to
enter the thermometer reading and then touch “OK”).
• Put the probe and thermometer into hot water (boiling
hot, if available). Follow the instructions in the SPARKvue Help page about “Calibration Point 2”.
• When finished, touch “OK” until you return to the graph
page.
Using Xplorer GLX Datalogger
• Refer to the Xplorer GLX Datalogger User’s Guide for
calibration instructions.
