*Response time will be less than 15 seconds after probe tip reaches desired temperature. The probe tip temperature will change at different rates
based on measurement medium. Ex: In still air probe tip may take minutes to reach desired temperature, in liquid bath probe tip may take only a
few seconds to reach the desired temperature.
