Mire Mysteries!

Delving into the physics store....does anyone have any idea what these are?! The black one has swivel feet to stand it up and the wooden one has a bit that slides up and down in the middle.

 

[MichaelGosden]

they look a bit like giant vernier scales

 

[KeithD]

They are large models of Vernier Calipers to show students how the scale works.

 

[Nick Mitchener]

Yes and very desirable, would love one.

Yeah, we've been on the look out for one too. We've thought of making one, the only place I've seen a decent one for sale is here:

Vernier Model - 1002951 - U15035 - Measurement of Length - 3B Scientific

Vernier Model | Measurement of Length | For demonstrating Vernier readings on length measuring devices and protractors.Length: 600 mmVernier length: 260 mmHeight: 190 mm

they come up at auction occasionally but not cheap.

 

[Paul]

How much does a full size 2M Vernier calliper go for?

 

[Nick Mitchener]

They are training aids to read vernier scales, not specifically calipers, I've never seen them as giant calipers just giant vernier scales. At auction I've seen them for a couple of hundred.

Wow, I'd better lock ours up then. It gets used with every class before they use real verniers for the first time.
