n: a type of thermometer used on oil tanks. The graduated part of the thermometer is angled at least 90ﾰ from the temperature-sensitive portion. The angle conforms to the shell of the tank and permits easy reading of the instrument.

n: a glass-stem thermometer in which the tail is bent at an angle to the stem so that the tail can be mounted in a horizontally disposed thermowell, leaving the scale vertical for greater ease of reading.

n: a corrosion-resistant metal case in which a glass-stem thermometer can be placed to minimise the risk of breakage.

n: a holder for a mercury-in-glass thermometer that incorporates a small metal container into which the bulb of the thermometer is inserted and that serves to hold a small sample of liquid the temperature of which is being measured. The liquid in the cup keeps the bulb sub-merged in liquid until the temperature is recorded.

n: a thermometer on which the temperature is indicated by a moving needle or pointer on a circular face or disk rather than with liquid in a glass or a liquid crystal display (LCD).
