Go Direct Thermocouple
Amplifier
(Order Code GDX-TCA)
Use Go Direct Thermocouple Amplifier to collect data from
K, J, or T type thermocouple wires (not included). Used in conjunction with our
K-type wire, it can measure temperature in the range of –200°C to 1400°C and can
be used for any of the following experiments:
Study how the temperature inside a Bunsen burner flame varies with position.
l
Compare the temperatures of different flames (candles vs. Bunsen burner).
l
Check the calibration of ovens.
l
Experimentally determine the melting point of copper, bismuth, or other solids.
l
Measure the temperature of dry ice or liquid air.
