Computer-Based Thermal Expansion (Discontinued) - TD-8579A
The change in rod length is measured by a rotary motion sensor with a special adapter pin that turns when in contact with the expanding rod.
Product Summary
Now students can see the length of the rod increase on a graph as the temperature rises. In this computerized version of the PASCO Compact Thermal Expansion Apparatus, the change in rod length is measured by a Rotary Motion Sensor with a special adapter pin that turns when in contact with the expanding rod.
The temperature of the rod is measured using a 10 kΩ thermistor. The included cable can be connected to either a PASPORT Temperature Sensor or a ScienceWorkshop Thermistor Sensor to read the temperature directly without need of a resistance-to-temperature conversion chart.
