Hello,
I need a dial caliper to measure simple car stuff like brake rotors and things like that.
If you have to choose between a digital or analog dial caliper wich one would you take?
thanks
-
Analog
-
Analog, but maybe because that is all I've ever had to use. I like to see the range.
-
Analog, because they always work, you don't have to worry about a battery, and t
hey are more dirt resistant.
but...calipers are not the right tool for measuring brake rotors..
They will measure the thickest point, you want to measure the thinnest point, you need a micrometer....
-
Agree with Rusty... unless you have ball tips for your caliper. I have both, I use my analog more because it is always ready.
the digital should not be stored with the batteries installed, normally takes several button type that can leak & corrode & cost $$.
but I use digital when I want MM/IN conversion or quick check of sizes, like checking 30+ allen wrenches, unmarked, mixed odds & ends.
just press button to switch between MM or IN.

I personally have a set of the cheap chinese import brake rotor calipers, they work well for that purpose. I take the battery out when I store them, I use them infrequently, so far no problem. Note that brake calipers are very different from a regular dial caliper - they need to reach in to the brake disk so you can find and measure the thinnest part. I have digital and analog "regular" calipers, I prefer digital for precision work but carry analog around in the car because the battery won't be dead when I need it.

I have trouble reading the ordinary vernier calipers (analog?) these days, even with glasses! I've picked a couple of S/H mechanical dial vernier calipers ( metric and imp..) and find them very user friendly and certainly no batteries to worry about!

Aha, showing our age, ordinary Vernier (split the lines) were great until the Dial Verniers came out.. and they are inexpensive now..

I'll go against the flow. I've had a digital caliper for over twenty years now, have never had problems, I use it frequently to check lumber thickness out of the sander. In all those years I've replaced the batteries twice. I'll have to say I've never used a dial caliper so I can't compare.

Depends on what you need it for.
I really like the little 4" pocket dial caliper from Horror Freight. Its like, 5 bucks when you are lucky enough to catch it on sale.
I have a laboratory grade micrometer and a "last word" jeweled dial indicator but the junker pocket dial caliper is plenty close enough most of the time
and if I drop it there is no funeral.

Rusty is right. I have been playing with becoming a home shop machinist for about 5 years now and have found that one type of measuring tool is no where enough. Regular micrometers are needed and the old dial calipers have their place also. A stop at your local Hock shop can produce some brand name instruments at a fraction of the original price. If you keep your eye out, you can pick up some great deals on electronic digital calipers for as little as $15. I have a pair on ever work bench and even my desk here in the computer room. As far as battery's go, they can be purchased on-line for as little as $3 a dozen, most of the time they will last about 5 months.

I am thrilled to report that I have been buying coin batteries for 99 cents a dozen, free shipping!
Ebay is loaded with them. You have to order from central China usually, but oh well.
That is where they come from anyway.

No need to send to China for them when Amazon sells Brand named battery's for cheap. and if you happen to have their "Prime" membership the shipping is paid. http://www.amazon.com/b?ie=UTF8&node=389581011
