Wide-Range Temperature Probe, order code WRT-BTA, $64.00
Specifications and User Guide

TROUBLESHOOTING
- Primary Test: Connect the sensor and run the data-collection program. Hold the tip of the sensor in your hand and check for the temperature readings to change.
- Secondary Test: Connect the sensor and run the data-collection program. Place the probe into an ice-water bath and/or place it into a boiling-water (or hot-water) bath.

OTHER TIL ENTRIES
- None

SPECIFICATIONS
- Range: �20 to 330 deg C (�4 to 626 deg F)
- Maximum temperature that the sensor can tolerate without damage: 380 deg C
- Accuracy: �0.1 deg C at 0 deg C
- Response time (time for 90% change in reading):
----- 14.5 seconds (in water, still)
----- 8.0 seconds (in water, with stirring)
----- 420 seconds (in still air)
- 12-bit resolution (LabQuest, LabPro): 0.10 deg C
- 13-bit resolution (SensorDaq): 0.05 deg C
- Probe dimensions:
------ length (handle plus body): 24.5 cm
------ Stainless steel body: length 17 cm, diameter 6.4 mm
------ Probe handle: length 6.8 cm, width 2.25 cm, thickness 1.3 cm
- Circuitry is built into the handle of the probe. For optimal accuracy of the RTD, keep the handle of the probe from warming above 40 deg C (104 deg F). Shield the handle from high-temperature using aluminum foil or other shielding material.
- Cannot be used with TI calculators in combination with EasyLink, LabPro, CBL, or CBL 2. Nor can it be used with Palm handhelds in combination with the LabPro interface.

CALIBRATION
- Calibrate? Never. Note: There is no method to perform a calibration of this sensor in any of our software programs; however, there is no need to do so.
