Instant-read thermometer

Also called a probe thermometer, this is technically classified as a bimetallic stemmed thermometer. It measures temperature through a metal probe that has a sensor in the end and typically is scaled from 0° to 220°F(–18°C to 104°C). The indicator head has a round face with a needle that registers at the numbered temperature markings. Most models have an adjustable calibration nut and slip into a thin tube with a holding clip, which allows you to attach the thermometer to your chef’s jacket.
