An instrument used to measure high temperature is

1. Pyrheliometer
2. Pyrometer
3. Technometer
4. Pyknometer

Correct answer: Pyrometer

Solution

A pyrometer is used to measure very high temperatures, often without direct contact. The other options measure different things: a pyrheliometer measures solar radiation, a pyknometer measures density, and a technometer is not for temperature.
