Termometr cieczowy – termometr, w którym pomiaru temperatury tworzy się przez pomiar objętości cieczy. Nakłada się z ze pojemnika z mieszanką, który istnieje zjednoczony z kapilarą szklaną, za której też cieczą szuka się gaz obojętny. Umieszczona wzdłuż kapilary skala umożliwia odczyt temperatury. Cieczą termometryczną jest kilkakrotnie rtęć lub gaz.
Termometr – dodatek do rozmiaru temperatury metodą pośrednią, na bazie zmiany pod wpływem temperatury właściwości termometrycznej ciała termometrycznego użytego w termometrze. Zakres mierzonych temperatur oraz wykonań termometru w sporym stopniu chce z ciała termometrycznego i wadzie termometrycznej. Termometr może sprzyjać do rachunku dowolnej temperatury w nazwanym charakterze lub podawania jedynie wybranych wartości temperatury (wskaźniki temperatury)
Najczęściej podawane idzie w termometrach
Podział termometrów ze względu na podstawę działania[edytuj]
termometr cieczowy – wykorzystuje zjawisko rozszerzalności cieplnej cieczy (przeważnie rtęci albo alkoholu):
termometr rtęciowy – dla temperatur od −38 °C (temp. topnienia rtęci) do +356 °C (temp. wrzenia rtęci);
termometr alkoholowy – dla temperatur od −70 do +120 °C; np. termometr pokojowy
Termometr bimetalowy, w którym monitorowanie temperatury urządzeń chłodniczych
przeznacza się różnice w rozszerzalności cieplnej dwóch metali.
termometr gazowy – czynnikiem roboczym jest alkohol, godzi się parametry gazu np. objętość przy stałym ciśnieniu lub ciśnienie przy stałej objętości.
termometr parowy – wykorzystuje zależność ciśnienia pary nasyconej od temperatury, brany w termostatach np. samochodowych,
termometr radiacyjny – pracuje na prawdzie pomiaru promieniowania wydzielanego przez ciała (np. pirometr lub kamera termowizyjna)
termometr elektryczny – wykorzystuje wpływ temperatury na własności elektryczne materiałów stosowanych do zawartości czujników.
termometr rezystancyjny – wykorzystujący zależność rezystancji metali i półprzewodników od temperatury. Materiały zaczynane w niniejszego wariantu czujnikach:
platyna,
brąz,
półprzewodniki,
specjalne stopy; patrz termistor;
termometr wykorzystujący zmianę różnicy potencjałów na kontaktach różnych produktów wraz z temperaturą
termoparę (termometr termoelektryczny) – wykorzystuje zjawisko Seebecka
termometr półprzewodnikowy.
Termometr lekarski – termometr specjalizowany do pomiaru temperatury ciała. Termometry te umożliwiają odczyt zmierzonej temperatury po zaprzestaniu pomiaru w porządku kiedy temperatura termometru spada (termometr temperatur maksymalnych).

Rozróżniamy parę sposobów termometrów lekarskich:

termometr ciekłokrystaliczny w sytuacje elastycznego paska, który można dodać do ciała;
termometr cieczowy, najczęściej rtęciowy; w kontakcie z zrezygnowaniem ze transakcji w UE rtęć jest reprezentowana np. przez galinstan, stop metali płynęły w temperaturze pokojowej;
termometr elektroniczny.
Odmianą termometru medycznego istnieje ponadto termometr owulacyjny.
