What device is used to check the processor temperature during daily checks?

• A. Thermometer built into the processor
• B. External thermometer
• C. Temperature strip on the door
• D. Digital thermometer in a separate meter

Answer: (A)

Monitoring the processor’s temperature is done with the thermometer built into the processor because it measures the actual temperatures of the development baths inside the unit. This internal sensor gives a direct, calibrated reading of the conditions that affect film development, so daily checks reflect what the chemical processes are experiencing. Using an external thermometer wouldn’t reliably capture the internal bath temperature, and a temperature strip on the door would only show ambient exterior conditions. A separate digital thermometer adds extra equipment and potential drift, whereas the built-in thermometer is already calibrated for the device and provides an accurate, immediate readout for QA purposes.
