He verified all his instruments—the map-holder, the compass, the altimeter, the tachometer, the speedometer—with searching care.

They had fired at me two hundred times: my bullets, before the breakdown, had gone through their altimeter and their tachometer, which had caused their excitement.
The case is made that radar altimeter data can be used to monitor changes in glacier topography related to climate change and surge events.
Such changes in snow structure are important as they may influence radar altimeter returns.
The altitude at each point was measured using an altimeter.
