What is the working principle behind ordinary in-situ temperature meters? Resistance thermometer? Thermocouple thermometer? Bimetallic thermometer? A bimetallic strip thermometer again? The measurement range is 0-200°C.

For ordinary in-situ temperature gauges, bimetallic thermometers are used.

Depending on your accuracy requirements, if no such requirements exist, use a bimetallic thermometer.

For applications requiring high precision, use a thermoresistive temperature indicator with local display, powered by AA batteries; for applications where precision requirements are lower and the operating environment is not harsh, use a bimetallic thermometer
