Response to "Comment on 'A versatile thermoelectric temperature controller with 10 mK reproducibility and 100 mK absolute accuracy"' [Rev. Sci. Instrum. 80, 126107 (2009)]

Abstract

The preceding comment by Sloman points out that the absolute accuracy of a temperature controller may be compromised by thermistor self-heating. We measured the self-heating of the thermistor used in our temperature controller, verifying a systematic error of nearly 200 mK. However, this error is reduced by over an order of magnitude with a slight change in our original circuit design. With this change, our controller does achieve an absolute temperature accuracy of 100 mK, limited mainly by the stated absolute accuracy of the thermistor used in the circuit.
