Digital Thickness Gauge 0.5inch, 0.00005"/0.001mm Resolution

Seems like a great product so far.

Now that I figured out how to use them correctly, I am upping my previous rating from 4 to 5 stars.

I've had this digital micrometer for about 15 months and have used it extensively. I would say between 10 thousand to 12 thousand different measurements. My range of measurements are between 1.5mm and 2.0mm mostly with a few larger. I've attached 4 different photos of linearity graphs of my unit against Precision Tools feeler gauges (2 graphs about 8 months apart), a more recent graph using McMaster Carr precision tool steel rods and a final graph which has the Precision Tools feeler gauges and two certified flat milled stainless steel plates to give a much broader range. I had absolutely no success using this micrometer as a hand held device, which is why I think it has some bad reviews. It's advertised as being a hand held device. I use the device when it is securely fastened to a lab stand. Zero can walk after repeated use, but always returns stable - keep it clean. Excellent for rapid repeat measurements

We rendered this tool unusable for our workplace. The tool almost never zeros out, and gives an inconsistent reading.

Good little caliper set just very difficult to keep level. Maybe different on other material tried to use on saw blades can’t hold steady for an accurate reading. Going to keep maybe come in handy soon.

Very happy with the purchase and the low cost! Perfect for my application in sales.

the jump from .001" to .0001" precision is huge when it comes to the instrument..001 is relatively low costbut not true of .0001 instrumentsexpect to pay 3-10x this price point for higher end units...so if you are needs are not that demanding and you dont use the device every day, this low cost unit might suffice for your needs... for me, most of the time, .001" is all i need, but on rare occassions i need more, and this little unit is pretty damn accurte, at least to +/- .0002 at a min.i don not see an accuracy spec on this, wold be nice to see, but using some high end units i own, i am finding it reasonably accurate as i wrote above....if you only need .001 accuracy, there is many many options...recommended...

The readings are inconsistent from one measurement to the next. It’s a nice design for measuring veneer thickness, comfortable, easy to read, it almost never returns to zero after one measurement, I can’t trust it so I’m back to my original vernier calipers.

Sim0le and easy. Works great. Using for research. Had to buy separate adapter for logging data directly to laptop, but worth it!

よい。

通常のマイクロメーターと値はほとんど変わりませんので、こちらで十分です。とっっっても楽です。たまに通常のマイクロメーターと比較して精度確認するくらいで良いでしょう。電源が充電式だったら良かったのですが、Micro-Bによる給電もしくは、LR44電池となります。LR44電池は未付属ですのでご注意ください。大変気に入りました。

No battery + instruction only in Chinese. Just received and return

緑のプラケースに日本語説明書と本体が入って届きます。説明書は簡単な物で、電池の入れ方（向き）とかは記載されてません。サイトの商品写真４枚目には英文で出力ポートのことと、バッテリーの予備が付属しているようなことが記載されてますが、日本語説明書には出力ポートに関しての詳しい説明は無く、別途、アイテムが必要なようです。また、バッテリーは付属してません。（サイトの説明には”国際運送のため、ボタン電池が付属しておりません”とは書かれてますが、商品写真と矛盾しています。）精度に関してはゼロ点修正もしっかり出来ているので、ほぼ正確だと感じます。厚さ測定は12.7㎜までOKの様ですが、最大で13.604㎜まで表示するので。もうすこし行けそうです。ちなみに挟む形状が平らな円形なので、挟み方によっては誤差が出そうです。ダイヤルゲージのような先細り形状が良かったかなと思います。
