Which thermometer type measures temperature through a ceramic probe and is generally used to check the temperature of liquids?

• A. Thermistors
• B. Thermocouples
• C. Source Contamination
• D. Spoilage

Answer: (A)

Thermistors are temperature sensors made from ceramic materials whose electrical resistance changes with temperature. Because the probe is ceramic, they’re durable and chemically resistant, which makes them ideal for measuring the temperature of liquids. They provide accurate, fast readings in the typical liquid temperature range found in food and beverage applications. Thermocouples, while versatile and capable of wide temperature ranges, use metal probes and rely on the voltage created by two dissimilar metals, not a ceramic-based sensing element. The other two options aren’t thermometer types at all; they refer to conditions (source contamination or spoilage) rather than sensing technology. So, a ceramic-probe thermometer aligns with thermistors, making it the best choice for monitoring liquid temperatures.
