Big display, smooth movement and accurate measuring

7410

7410

7410

Measure what you want the way you want

Measure up to 6 inches with an accuracy of 0.001”. The caliper has a zero reset button to assure accurate measuring. It also has a convenient button to change the display from inch-fractions, decimal inch or millimeters. The caliper is water and dust resistant rated IP54.

Measures in four ways and displays in three

The caliper measures in the typical four ways of a Vernier caliper. It measures external, internal, step and depth. The caliper displays measurements in inch-fraction, decimal, and metric. The inch-fraction shows down to 1/64 of an inch which is useful in woodworking and other activities. The battery compartment is located out of the way so it doesn’t pop out during use.

What you need for precision measuring

The Digital Fraction 6” Caliper comes in a hard protective case and includes two CR2032 batteries, one for the caliper and a bonus one as a spare. Plus the caliper has a user’s guide that covers how to use and maintain this precision measure.

Product Description

Perfect for pro and hobbyist woodworkers, cabinet makers, metal crafters, mechanics, reloaders and serious workshop DIYs. The AccuMASTER' S precision ground measuring faces and hardened stainless steel ruler and jaws are designed to measure up to your workshop demands. EASY TO SEE AND USE! – Extra large LCD display featuring oversized 5/8” main digits drastically improves visibility and usability in shop environments. No more small dial faces or hard to read Vernier scales, nor tiny digital readouts of mixed decimal and fractions on the same screen. PRACTICAL 1/64” FRACTIONS – most woodworkers want precision and they want it in the familiar format of inches and fractions, but they also need it to be in a usable format -- it’s not helpful to see 53/128” if your tools (and your eyes) only read to 64ths! AccuMASTER solves this and also gives you decimal inches and millimeters if the job requires. SMOOTH AND EASY OPERATION – unlike many in this price range, the AccuMASTER glides smoothly along the stainless steel ruler as the slip-resistant thumb roller allows precise stops for the most accurate measurements. The clamp screw lets you lock the slider at any position desired. The Mode key toggles between Inch-Fractions, Decimal Inch and MMs. The “alternate-zero” lets you reset to zero at any point for fast and easy relative measurements. On/Off button and auto-shut-off ensures long battery life. SPECIFICATIONS -- Accuracy 0. 001” (0. 02mm); LCD Display Resolution 0. 0005” (0. 01mm) 1/64”. Range 0-6” and 0-150mm. Comes with CR-2032 battery, sturdy foam-lined case and a 2-year . BONUS BATTERY – includes spare CR-2032 so you’re always prepared! Plus, the secure, easy access battery door stays firmly closed, will not slide or pop off and get lost as with lesser brands. Why would you put up with less-featured, harder to read digital calipers in YOUR shop? Click Add to Cart now and get the new AccuMASTER today!

Perfect for my needs
I wasn't expecting much at this price-point, but I got tired of trying to use a magnifying glass to read my 1960's era caliper. I don't build rocket-ships that require extraordinary precision. I'm just a DIY guy. I was very pleased to see that this digital caliper gave me consistent and __exact__ measurements when reading the leaves on my General 230 feeler gauge. Not just close, but exact. Good enough for me.Update 10/2022: Still a five star product, despite a problem. I'd add a sixth star if I could. My 7410 stopped working, even after a battery replacement. I emailed Calculated Industries and explained my problem. I made a note on my calendar to be sure I got a reply after a few days, but I had a reply in less than an hour! The reply was personal, not a canned CSR response from a troubleshooting manual. They gave me a couple of things to try (none worked), and they suggested I return it for a warranty replacement. I shipped it back and had a brand new working caliper within a week of my original email. This level of customer service is rare nowadays. Six stars!

The display is really easy to read. A CR2032 battery is pre-installed, and it comes with a spare. It's very accurate and precise. It is as accurate as my 45 years old Craftsman Dial Calipers and made well. This unit also matches up with my Mitutoyo 0-1" micrometer within .001". Not bad for something made in China and sells for a tick under $40. I would not hesitate for a minute to pick up another one. These are hard to beat. It's easy to use and operates smoothly.

Feels high quality also the different settings you can use and the sturdiness of this tool is high quality. Also came accurate out if the box.

So I originally bought these as a cheap alternative to my Starrett calipers, however I have found my self using them more. They are cheap, have a huge easy to read screen at a glance, can use MM, Inch and fractions. I have found that these are truly as accurate as my Starrett calipers and made almost as well. As for battery life, I've change it once in two years and used it every single day so that's just amazing. I personally would not hesitate for a second to pick another on of these up, If you want the best cheap calipers then these truly are hard to beat.

I mainly bought this for my guitars. Once I figured out how to measure depth at the other end I love it!🙃 big screen, easy to read. Feels a little lose(not bad). I’m in my 40s n think of heavy and tight when it comes to quality tools. Based on that I wouldn’t recommend this for a professional but it’ll prob last me until I forget about it n battery blows up n I’ll discover that when I need it! But that’ll be on me! For $30 def 5 stars. If u need for work prob spend $100 more n get a better one but I could be wrong!

Reviewed in the United States on October 30, 2022
Style: 6 " Digital Caliper - Frac/Inch/MMVerified Purchase
I have limited use for a caliper but, it is critical. I've gone through several other calipers that didn't work out of the box, worked a few times then quit or gave false readings. I would take a measurement, reset and measure again and get a different reading. I began looking for a more complicated and expensive caliper when I found this one. After wasting money on the others and being hesitant to waste more I decided to try this one. So glad I did. The AccuMaster is exactly that. Consistent readings, immediate conversions,
well built and easy to use (smooth). Well worth the money and peace of mind. Buy it!
