Inclinatorium Value Guide

The Inclinatorium is a specialized scientific instrument from the 1800-1850 era designed to measure the Earth's magnetic dip or inclination. These European brass and steel devices are highly collectible due to their historical role in advancing geomagnetism and global maritime navigation.

What Is Inclinatorium Worth?

The typical price range for Inclinatorium is $800 - $1,000 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Mechanical integrity and the ability of the magnetic needle to swing freely without friction.
• The presence of original protective glass housing or a fitted wooden transit case.
• The complexity of the scale engravings and the overall condition of the brass patina.
• Historical provenance, especially if linked to specific scientific expeditions or known instrument makers.

How to Identify Inclinatorium?

• Look for a vertical circular scale graduated in degrees, typically crafted from engraved brass.
• Verify the presence of a finely balanced steel magnetic needle mounted on a horizontal axis.
• Check for European maker marks or scientific instrument signatures common to the early 19th century.
• Examine the leveling base, which often features adjustable screw feet for precise calibration.

History of Inclinatorium

Developed in the 16th century, inclinatoriums were crucial for understanding the Earth's magnetic field. They helped mariners and scientists determine latitude and were instrumental in the study of geomagnetism, providing insights into the planet's inner workings. Early models were simple, but they evolved into precision instruments used in expeditions around the globe.
