Which statements regarding daily checking of processor developer solution temperature are TRUE?

The accurate statement regarding the daily checking of processor developer solution temperature is that it is tested by the thermometer built into the processor and the performance criteria is ± 0.5°F.

This is important because maintaining the correct temperature of the developer solution is crucial for producing high-quality radiographs. The built-in thermometer provides a convenient and accurate way to monitor the temperature without the need for manual intervention or additional tools. Additionally, having a performance criterion of ± 0.5°F ensures that the temperature remains within a narrow acceptable range, which is vital for consistent development of film and the integrity of imaging results.

In this context, other statements do not fully capture this critical aspect. Although they may mention different elements related to temperature checks, they either do not specify the method used for measurement or omit the precise performance criteria necessary for proper operation. Thus, the statement chosen emphasizes both the method of measurement and the tight tolerance needed for effective temperature control in the radiography process.
