Question:
Which of the following is correctly matched?
Which of the following is correctly matched?
Show Hint
Associate "Hypso-" (from Greek meaning height) directly with "Hypsometer," which is the standard term for any height-measuring instrument in forestry.
Updated On: Jul 21, 2026
- Clinometer - Density
- Altimeter - Atmospheric pressure
- Hypsometer - Height
- Relaskop - Light intensity

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Forest mensuration relies on specialized instruments to measure different tree and stand variables, including height, diameter, canopy density, and basal area.
Step 2: Detailed Explanation:
Let us evaluate each option to find the correct instrument-measurement pairing:
- Option (A): Clinometer - Density: This is an incorrect match.
A clinometer is a hand-held instrument used to measure angles of elevation or depression, primarily used alongside horizontal distance to calculate tree height, not stand density.
- Option (B): Altimeter - Atmospheric pressure: This is an incorrect match.
An altimeter is used to measure altitude above a reference level.
While barometric altimeters function by sensing changes in atmospheric pressure, they are calibrated to output altitude (height above sea level), not direct atmospheric pressure measurements in a forestry context.
- Option (C): Hypsometer - Height: This is a correct match.
A hypsometer is a specialized class of instruments designed to measure the height of standing trees based on trigonometric or geometric principles.
Examples include the Christen's hypsometer and the Faustmann's hypsometer.
- Option (D): Relaskop - Light intensity: This is an incorrect match.
The Spiegel Relaskop is a multi-functional instrument used in forest inventories to estimate stand basal area (using angle-gauge principles), measure tree height, and determine stem diameters at various heights, not light intensity.
Thus, Option (C) is the only correctly matched pair.
Step 3: Final Answer:
The correctly matched pair is Hypsometer - Height.
Forest mensuration relies on specialized instruments to measure different tree and stand variables, including height, diameter, canopy density, and basal area.

The correctly matched pair is Hypsometer - Height.
