• Modern hypsometers can provide accurate altitude readings within a few feet.
• The research team carried portable hypsometers during their geological expedition.
• Hypsometers are essential tools for creating topographic maps.
• The meteorologist calibrated the hypsometers before the weather balloon launch.
• Digital hypsometers have largely replaced the older barometric models.
