As I continued to make videos about tech, I wanted to upgrade some of the tools
that I use to show it off and describe it hey guys i'm tom and welcome back to
the channel today we are going to be looking at a tool that measures that is
the carbon fiber digital caliper well I would typically just unbox this guy
there's not a lot going on in the packaging department here so what we're
gonna do is just test it we have a couple of coins sitting in over here I
know the exact thickness of these said coins and we're gonna kind of test how
accurate this caliper is with things that are standard in measurement so
let's just get right into it so I picked up this particular caliper on Amazon for
just under $10 if you guys are interested in looking at or purchasing
this guy I'll make sure to throw Amazon affiliate links below so it comes with
two batteries we'll open these guys up and first impressions is this is most
definitely not carbon fiber this is most definitely plastic which I'm not I'm not
surprised there's calipers oh there's already
batteries in it extra batteries I kind of wish I tested that before I went and
opened them I'm not losing those so beyond the caliper just kind of
instantly feeling chintzy it does seem to be pretty smooth so I don't know a
lot about calipers but I do understand that there are obviously two edges to
this one one to measure the thickness of the outside of an item and then this
side over here is to measure the inside of an item say like a roll of tape
kind of cool so I have two sets of 2019 coins nickels dimes and pennies I don't
know why I put them in that order let's just start with pennies and then we'll
move up the ranks of coins the thickness of a penny is 1.5 to milliliters
millimeters by 1.5 to millimeters so let's see so you can zero it out and
there's a instant off button I'm not sure if this is gonna work but 1.5 no
this is the thing with this calipers I can definitely push it further than than
just the outside of this where it definitely has a little bit of give and
should this be able to slide in and out so like Annie pushing on it and make it
1.5 though I'm pretty sure I can make it 1.4 no 1.5 I wish there was another
decimal place would be able to really test the be able to really test this
okay these pennies are okay in my book the next thing we're gonna test is the
nickels a nickel is one point nine five millimeters so put this caliper back on
I mean this is pretty tight free that's what she said that's saying to point to
this is not a special nickel I can't even get it to force down to 1.95
literally at two point to two point five two point to two point one let's try
this other nickel slide it right in there
that's what she said this one's a little closer all right wait so here we go I
don't know if the testing area for a caliper is supposed to be the tip or
this this further back area because if it's the further back spot it might be
closer to one point nine five where this tip is catching the the lip of the coin
I'm not I'm not 100% sure but I'm gonna say that those two nickels are not
coming in at an accurate one point nine five if you consider five one hundredths
of a millimeter I think that's correct I don't know if I'm wrong I'm sure you
guys will let me know in the comments regardless I mean they're closed for
what I need them for they're super close all right and a dime lastly is one point
three five millimeters so right at the tip that's coming in at one point for
further in the back yeah one point for those one's pretty pretty on point to
the other 2019 dime 1.5 oh that's one of them thick dimes
I don't know I mean it's constantly going back to zero it feels like if you
gotta see me pushing on on the caliper it it seems to go into like a negative
range when I'm distributing a little bit of extra pressure which seems like it
should be at least like another decimal place if it's that small of an increment
regardless this does go up to almost six inches there it is six inches should be
technically right there because this has inch marks zero one two three four five
and six it does seem to be somewhat accurate but definitely not a hundred
percent accurate from what I'm seeing but beyond that thank you guys for
watching I hope you enjoyed this video be sure to subscribe if you haven't
already and I will see you in the next video peace
