Titanium Alloy Circular Slide Rule Calculator Pendant TITANER TRP026G

This circular slide rule is a compact titanium tool from TITANER, combining a working analog calculator face with a curved measuring edge and a pendant format. The two rotating rings carry logarithmic and natural-number scales for multiplication and division, while the opposite face supports addition and subtraction.

Features

• Rotating two-ring design with a logarithmic scale face and a natural-number scale face
• Addition and subtraction read on the face without the logo; multiplication and division on the face with the logo
• The outer ring turns to form a simple ring gauge for measuring irregular curves
• Precision laser-engraved fine graduations on a circular scale
• Can be worn or carried as a pendant

Specifications

Dimensions and weights are approximate values; slight variation can occur with production batch, surface finish and manual measurement.

Choosing a Version

Two versions are offered. The retro copper-titanium version uses a titanium outer ring with a phosphor bronze inner ring. The future titanium version is made of TC4 titanium alloy throughout. Select the version you want before adding the item to your cart.

FAQ

How do I read the scales?

Line up the zero marks on the inner and outer rings to start, then rotate the outer ring to set the number you are working with and read the result on the opposite ring. Addition and subtraction use the unmarked face; multiplication and division use the face carrying the logo. If a result passes one full turn on the addition face, add 10; on the multiplication face, multiply by 10.

Is it a precision calculating instrument?

No. It is intended as an aid for learning the principle of logarithmic calculation. Due to the nature of the engraving, the fine graduations can carry slight tolerance and it is not a precision calculating instrument.

What is the difference between the two versions?

The retro copper-titanium version has a TC4 titanium alloy outer ring and a phosphor bronze inner ring. The future titanium version is TC4 titanium alloy throughout. The stated weights differ slightly between the two.

What can I measure with it?

With the inner ring held and the outer ring turned, it works as a simple ring gauge, which can be used to measure irregular curves.
