\r<\/span> <\/span>溫度計是測溫儀器的總稱。根據(jù)所用測溫物質(zhì)的不同和測溫范圍的不同，有煤油溫度計、酒精溫度計、氣體溫度計、電阻溫度計溫差電偶溫度計[1]<\/span><\/span>、輻射溫度計和光測溫度計、雙金屬溫度計等。雙金屬溫度計是指專門用來測量500<\/span><\/span>℃<\/span>以上的溫度的溫度計，有光測溫度計、比色溫度計和輻射溫度計。雙金屬溫度計的原理和構(gòu)造都比較復(fù)雜，這里不再討論。其測量范圍為500<\/span><\/span>℃<\/span>至3000<\/span><\/span>℃<\/span>以上。
