42 Volume 85 • Number 3 A D VANC EME N T O F T H E PRACTICE thermometer is 0–220 °F (-20–110 °C). You will also need two containers of the same material type, such as inexpensive insulated travel mugs. Fill one container with cold tap water and the other with hot tap water; immerse the temperature standard liquid-in-glass thermometer in either container along with the probe of the electronic thermometer or the mechanical thermometer to be tested. Let both thermometers equilibrate (a few minutes will do) and compare the temperature reading of the temperature-standard thermometer against that of the thermometer being validated. Repeat the process in the other container. Always record your results. We use a bound composition book that is admissible in court and enter the time, date, and results that include the temperature of the temperature standard thermometer versus the field thermometer, along with your initial or signature. We use a separate column, marked in red ink, to list the correction factor (± variance from the standard) that we will apply in the field when taking temperatures. The results recorded in a bound composition book are a legal document that verifies due diligence in the performance of our duties as environmental health professionals. The process is simple, fast, accurate, inexpensive, defensible, and best of all, it cannot be challenged. Contact: firstname.lastname@example.org.
