Introduction

The Fast Response Temperature Probe (PS-2135)
measures temperature in degrees Celsius (-30 °C
to +105 °C) and plugs into any PASPORT™
Temperature Sensor, or ScienceWorkshop®
Thermistor Sensor. The Fast Response
Temperature probe has applications for studying
temperature gradients, evaporative cooling,
outdoor air temperature, and environmental
studies.

The probe can be placed on the surface of an
object, on skin, in water, or even in mild chemical
solutions. It has a 1-meter flexible wire, making it
convenient for taking measurements in long
flasks, between objects, or below the surface of a
liquid. The adhesive mylar foam covers are
designed to hold the probe tip and adhere it to a
participant’s skin or to other flat surfaces. The
mylar reduces environmental influences.

Setup Procedure

1. Insert the stereo plug on the Fast Response
Temperature Probe into the port on a PASPORT
Temperature Sensor box or a ScienceWorkshop
Thermistor Sensor.

2. Connect the Temperature Sensor to either a
PASPORT interface or a ScienceWorkshop
interface.

3. To collect data, place the probe in the liquid or
object to be measured. Open DataStudio, and
click the Start button. Follow the procedure to
set up a trial and start collecting.

4. Place the adhesive mylar foam disk on a
smooth (preferably hairless) skin surface

1. Remove one of the adhesive mylar foam cover
disks from the sheet set.

2. Carefully remove the protective backing paper.

Procedure Notes:

• Calibration of the PS-2125 Temperature Sensor

and Thermistor Sensor are generally not required.
However, if you wish to calibrate the PS-2125,
follow the instructions on the card supplied with
your sensor or in the DataStudio online help. If
necessary, download the instructions from
PASCO’s website (www.pasco.com).

• If using the probe with the Thermistor Sensor, set

up your experiment in DataStudio before collecting
data. (i.e. In the Setup window, click on the
Thermistor Sensor icon and drag it to an analog
channel on the picture of the interface.)

Safety Precaution

To prevent damage to the probe, do not use the

probe in an open flame, on a hot plate, or beyond
the recommended temperature range.

3. Place the Fast Response Temperature Probe
