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”.
