Sensor Usage Tips
PASCO Equipment used with the
pH/ORP/ISE with Temperature Sensor
• Compare ORP of water from a faucet, fish tank, and a pond.
• Discover how long chlorinated tap water needs to stand before adding to a
fish tank. Analyze the effect of temperature on this process.
• Study the effects of temperature on pH in a buffer
• Observe the heat of neutralization in a titration
• Measure the freezing and boiling point of a solution
• Study the effects of temperature and dilution on buffers
CARD 2B Calibrating the Temperature Probe
Calibration of the temperature probe is not usually required. The accuracy of the
PASCO temperature probes is better than 0.5
° C across the entire range of the
probe. However, the probe may be calibrated using the following procedure.
1. Plug the PS-2147 Sensor into a PASPORT interface connected to a USB-
compatible computer.
2. Insert a temperature probe into the sensor box using the 3.5 mm input on
the right side of the sensor box.
3. Click the Setup button in the DataStudio toolbar. The Setup window will
open.
4. Click on the Temperature Calibrate button in the Setup window. The
Calibrate window will open.
5. Place the temperature probe in an ice water bath.
6. Ensure the value in the dialogue box for Point 1 is 0. This value may be
changed to the temperature of the controlled temperature bath if it is
different than 0
° C.
7. Click the Set button adjacent to the Point 1 dialogue box.
8. Place the temperature probe in boiling water.
9. Ensure the value in the dialogue box for Point 2 is 100. This value may
be changed to the temperature of a controlled temperature bath if it is
different than 100
° C.
10. Click the Set button adjacent to the Point 2 dialogue box.
11. To save the calibration values, click the OK button. The calibration is
complete.
