We measured the temperature of a water bath with three types of thermometer set at 0.5{\textdegree}C increments between 32.5{\textdegree}C and 38.5{\textdegree}C and compared the values to a control. We recorded the time to display steady-state temperature. The Microlife thermometer most closely approximated control temperature (mean difference \<0.1{\textdegree}C (SD\<0.1{\textdegree}C)) and displayed a reading in a mean time of 29 s (SD 2 s). Used in {\textquoteleft}predictive{\textquoteright} (default) mode, the Welch Allyn SureTemp Plus 692 thermometer differed from the control by a mean of 0.6{\textdegree}C (SD 0.3{\textdegree}C), displaying a temperature at 15 s (SD 3 s). This device consistently overestimated temperature. In {\textquoteleft}continuous{\textquoteright} mode, the mean difference was \<0.1{\textdegree}C (SD\<0.1{\textdegree}C) at 5 min. The Phillips probe differed from the control by a mean of 0.4{\textdegree}C (SD 0.2{\textdegree}C). Thermometers used to measure temperature in newborn infants may underestimate hypothermia. A prospective study in newborn infants is needed.Data are available upon reasonable request.}, issn = {1359-2998}, URL = {https://fn.bmj.com/content/106/4/435}, eprint = {https://fn.bmj.com/content/106/4/435.full.pdf}, journal = {Archives of Disease in Childhood - Fetal and Neonatal Edition} }
