Planimeter

Hello,

I'm looking for a planimeter (metrics if possible). It is almost impossible to find one in France, and the only place I found on the net do not ship outside the US.
A used one will do the trick...
Thanks

 

How is your German?

Seem to remember

that "Plannix"(sp?) make a good metric planimiter, last time I bought one.

Perhaps a google search might turn up something?

Cheers!

 

Try the Lasico in the US.
They are well priced and work smart.
Try their web : http://www.lasico.com/
I have designed in old pencil+calc+planimeter days with a L10 very basic type and it worked with great accuracy, and it is priced at 239 $ nowadays...

I hope this helped you.
Good luck.

Are you familiar with the blade type planimeter? It is easy to make and won't cost more than a couple of dollars.

Gonzo,
I know somewhere I've seen a drawing of a homemade planimeter and how to use it. Can you elaborate on the above post? Sam

 

As of right now, there are 10 of them up on eBay. You probably don't want the small K&E's, used for map measurement and (for the antiques) calculating horsepower from steam engine indicator diagrams, but there looks like there are at least 5 that would be useful for NA work.

Cheers,

Earl

 

Thanks for all your answers.
I managed to buy a K&E planimeter at a reasonable price.
That should get me going for a while.

 

Hello,

I am looking for a planimeter and found many model from digital to conventional, from long arm to short arm, from roller , disc and stationary.

So my question is which is a good brand, trustworthy planimeter that do the work for boat designer and can be keep for a lifetime?

I may not use it intensively but would like to buy a good brand for keeping one as my vital instrument collection.

Thanks

I'll second the LaSico model. I managed to find an L30 for under $200 on ebay. The unit was brand new and works great. The L30 allows you to adjust the length of both arms giving quite a range of measurement. It's very easy to use and the little manual that came with it explained everything clearly. Maybe not as 'classic' looking, but very well made.

 

I bought a lietz zeroing planimeter on ebay several years ago. It no longer zeros,and I'm sceptical of it's accuracy. Price was great but just buyer beware on ebay!

 

I was overbidded always on ebay, so I think I look into LaSico planimeter website but would also look into HAFF planimeter, I would prefer second good condition planimeter than new out of the oven product.
