Figure 1. System calibration and performance evaluation.

(A) System calibration constant determination using distilled water as the thermal standard liquid at 0, 5, 10, 20 and 40 ºC. Data represent mean ± standard error of the mean (S.E.M.) of five repeated measurements. (B) Linear response curve of system calibration constant with regard to ambient testing temperature variation. Data represent mean ± S.E.M. of all fifteen repeated experiments per temperature condition.
