[Nhcoll-l] Digital calipers for museum use

[Elizabeth Wommack]

Thanks for the recommendation Nate.

I've heard another good recommendation for the iGaging as well in response to my question.
Some things are pretty hardy, but I think I would count small skulls (shrews, hummingbirds), and eggs as crushable. But then there are all of the larger things.
I do like the sound of the increased precision.

I'll add both to the list to look at.

cheers,
Beth

I use a SPI digiMax 30-440-2, which is a fiberglass digital caliper. It works really well. I have hated every other pair of fiberglass digital calipers I have ever encountered, but I’ve tested this model against a set of iGaging Absolute Origin calipers in the museum and have not found major differences in accuracy, though the iGaging model is more precise (to +-.001, if memory serves, whereas the digimax only goes +-.1).



I would recommend the iGaging Absolute Origin Calipers if you are measuring objects that are not fragile or crushable. They’re nice because you can hook them up to a computer via USB data cable for automated measurement entry. Would LOVE it if there were an accurate fiberglass caliper with a data cable.

Hello everyone,



Happy almost Friday everyone.



My museum is looking at getting a set of digital calipers for measuring mammal objects (but also hopefully useful or other vertebrate groups).



I have digital calipers I use myself for bird banding (Fowler brand), but I was wondering if other people had thoughts or opinions on brands and models?

I love my digital calipers (they've put up with a lot and gone with me many places), but I will say they are heavy, and I have to be very careful when I use them with small birds and objects.



We have a number of manual calipers (SPI Polymid Dial calipers), but we are hoping to get a nice pair of digital calipers for museum use as well.



cheers,

Beth
