Kynup Digital Caliper, 6 Inch IP67 Waterproof Caliper Measuring Tool

Some things that just cannot do without this. So then we buy one , a good quality product which is a must have. I didn't find anything bad or wrong with it unless you were measuring diamonds ! And if it would do right by you or not I don't know.

Seems to work, accurate as far as I can tell

Just received. Very good delivery time. Battery was drained when it arrived. On/Off switch sensitive. Suspect caliper turned on during shipping. Replaced battery with one of 2 provided. Seems like a clean, functional design. Easy to use, though a bit heavy. Large display numbers. Easy to read. Easy to change from mm to dec in to fraction in. Very fine readings for accuracy. I have no reliable means of verifying calibration accuracy available. For my wood shop it will be close enough. Quality seems good. Nice plastic case with battery compartment screwdriver and 2 batteries well secured in case. For $20, before tax, well worth the money for my hobby shop.

Great Caliper with a durable case. I use the caliper to check image registration on paper that runs through printers. The measurements are accurate in inches or millimeters. The construction is durable and not easily bendable. Easy to use and reliable. Battery will last a long time. There is smooth movement when using the positioning wheel to expand the caliper. Great product for the money. Easy to read display and easy use.

I got this because I recently got into 3D printing and needed a way to get better measurements. I had originally purchased a different one, but it didn't include the fractions function. Not sure that I'll use it too often, but I'd rather have the option. This kynup caliper was a reasonable price and has, so far, been great. The metal feels durable, and it slides easily for measuring. The plastic storage case is decent quality, and the included extra batteries are appreciated. The tolerances are very good. I know they're not spot on, but that's to be expected at the price. They claim accuracy +/- at no more than .04mm, which seems to be close to what I'm seeing, but it might be slightly more at larger distances. However, the accuracy has been very good for modeling 3D objects for printing. I designed a battery case for my 80V tools, so that I can use it across a couple brands of yards tools. This thing helped me get it almost exact.

Really nice Caliper. Very accurate / precise. Simple to operate and battery lasts a long time. Would certainly buy this product again!

A very useful tool for 3D printing.

I was choosing between this and a manual dial caliper, so I ran some bench tests to see how they compared. I used reference blocks from my micrometer set, and interestingly, both the analog and digital units showed zero errors at the 1", 2", 3", and 4" marks. Since battery drain is the main downside of digital tools, I checked the power consumption with a multimeter. This unit draws 17 µA when on and 15 µA when off. With a standard LR44 battery (150 mAh), that translates to about 10,000 hours (or 416 days) of storage life. Even though accuracy was a wash between the two types, I went with this unit because the digital display is easier to read and being able to toggle between inches, millimeters, and fractions is very convenient. It’s been solid so far, but I’ll have to see how the electronics hold up over the long term.

Bester Messschieber für eine Prüfung. Einfach zu bedienen und abzulesen

Excellent digital caliper that I've already used a ton of times around the house. Great value. As tested by Project Farm.

Junk.

Easy to operate, and auto turn off works, without flattening battery. Been using this for some time now, and it makes a great cheaper alternative to Mitsubishi. I also have the Non IP67 version, that unfortunately does not auto turn off.

The product arrived already in heavily used condition with excess oil and many scratches on it. It does work and it does give accurate measurement, but the build quality is not that good. Either go for cheaper one that is as bad as this and does the job just as well or go for a more expensive one that is reliable and good quality.
