			Casing
			The casing of a temperature and humidity meter houses and protects the electrical circuitry which powers the device. The casing is robust and ergonomic (easy to hold), making the tool hard-wearing and simple to use.

			Sensor
			The sensor is the detecting part of the instrument and is usually located at the end of a probe. For more information on how this works, see: How does a temperature and humidity meter work?

			Display
			A temperature and humidity meter has an LCD (liquid crystal display) screen, which displays the readings, as well as any informative symbols to clarify which unit and mode the device is in. Other symbols on the display can indicate low battery, or memory slots (see below).

			Buttons
			There are various buttons on temperature and humidity meters. Buttons which do the same thing can have alternative names on different models. You will need to read the user manual for each particular device to clarify. These are the most common types of button that can be found on temperature and humidity meters:

			Power This simply turns the device on and off.

			Function A temperature and humidity meter can generally display two of the different measurements at a time, the default usually being temperature and humidity. In order to change the displayed reading to wet bulb or dew point there will be one or more buttons. These can be named “Function”, “DP/WB” or similar.

			Unit There should be a button to change the unit of the temperature reading between degrees Celsius and degrees Fahrenheit.

			Hold A hold button allows you to freeze the current reading on the display.

			Min and max This button, or buttons, will change the display to the minimum or maximum readings taken during the current usage session.

			Memory Press this button to store the current reading into one of the device’s memory slots for comparative purposes. These can generally be recalled until the reading is deleted or replaced.
