An Altimeter
---
Traditionally, an Altimeter, which works by measuring air pressure. Air pressure decreases as you get higher in a nice reliable linear fashion, so you can use air-pressure to measure altitude. You'll get errors with weather changes, like when that nice low pressure storm front rolls in, your mountain suddenly measures a few meters higher, but its good enough for general use.
And to be much more fashionable, you can use a GPS receiver. The Global Positioning System will tell you not only your latitude and longitude, but also your altitude. And its way more accurate than a traditional altimeter.

Used to be trigonometry, but now they use GPS.

An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. See related link The altimeter measures the height above the ground and has a pointer which is adjustable depending in which air field you are taking off on. it measures the pressure of the air as you get higher off the ground the pressure reduces therefore it is able to determine your height above ground.
An altimeter is a piece of apparatus which measures someone's altitude.
A tape measure.
This instrument is a balance.
