You will never have that awkward situation where your caliper battery dies just when you need to take a measurement. Sure, if you have the budget, we recommend these near-indestructible high-end Mitutoyo calipers. But these are very fine calipers as well. The jaws are plastic, so not good for hot metal measurements or when you need perfectly flat jaws.In particular, these caught our eye since they are solar-powered and have a battery backup. Perfect for sustainable measuring in the hot desert. Or just when you keep coin batteries stocked at all times. If you're in a lit area (where the lux rating is over 200), the solar panel will power the calipers. Alternatively, if you're in darker surroundings (like in your secret underground lair and the power just went out), the 3V battery will take over. Note that the battery is not rechargeable, its just a backup supply. One button converts the measurement from millimeters to inches, and they're perfect for measuring components.Please note that to make shipping easier, a CR2016 battery is not included. As mentioned, it's not required - the calipers will run on solar power. However you can pick up a CR2016 battery from us or your local corner store.One thing to note is that you will need to zero the calipers when turning them on. It's no big deal - just close the jaws after turning on, and press the Zero button.Check out our calipers tutorial here. While these aren't as fancy as the Mitutoyo Digital Calipers, many of the same instructions apply!Note: Color of calipers may vary!"}}</script> <div class="row product-info"> <div

Sure, if you have the budget, <a href="https://www.adafruit.com/product/294">we recommend these near-indestructible high-end Mitutoyo calipers</a>. But these are very fine calipers as well. The jaws are plastic, so not good for hot metal measurements or when you need perfectly flat jaws.</p><p>In particular, these caught our eye since they are solar-powered <em>and</em> have a battery backup. Perfect for sustainable measuring in the hot desert. Or just when you keep coin batteries stocked at all times. If you're in a lit area (<a href="https://en.wikipedia.org/wiki/Lux">where the lux rating is over 200</a>), the solar panel will power the calipers. Alternatively, if you're in darker surroundings (like in your secret underground lair and the power just went out), the 3V battery will take over. Note that the battery is not rechargeable, its just a backup supply. One button converts the measurement from millimeters to inches, and they're perfect for measuring components.</p><p><strong>Please note that to make shipping easier, a CR2016 battery is not included. </strong>As mentioned, it's not <em>required</em> - the calipers will run on solar power. <a href="https://www.adafruit.com/product/2849">However you can pick up a CR2016 battery from us</a> or your local corner store.</p><p>One thing to note is that <strong>you will need to zero the calipers when turning them on</strong>. It's no big deal - just close the jaws after turning on, and press the Zero button.</p><p>Check out our calipers tutorial <a href="http://learn.adafruit.com/calipers/overview">here.</a> While these aren't as fancy as the <a href="http://www.adafruit.com/products/294">Mitutoyo Digital Calipers</a>, many of the same instructions apply!</p><p><strong>Note:</strong> Color of calipers may vary!</p><p><lite-youtube videoid="2Oh6qffx878" title="Calipers: Pin Pitch - Collin’s Lab Notes #adafruit #collinslabnotes" style="background-image: url(https://cdn-shop.adafruit.com/ytimg/vi/2Oh6qffx878/hqdefault.jpg)" params="" > <a href="https://www.youtube.com/watch?v=2Oh6qffx878" class="lyt-playbtn" title="Play video"> <span class="lyt-visually-hidden">Play video: Calipers: Pin Pitch - Collin’s Lab Notes #adafruit #collinslabnotes</span> </a> </lite-youtube></p><p><lite-youtube videoid="602rul1t2lg" title="New Products 2/7/2018 @adafruit #adafruit" style="background-image: url(https://cdn-shop.adafruit.com/ytimg/vi/602rul1t2lg/hqdefault.jpg)" params="start=132" > <a href="https://www.youtube.com/watch?v=602rul1t2lg&t=132" class="lyt-playbtn" title="Play video"> <span class="lyt-visually-hidden">Play video: New Products 2/7/2018 @adafruit #adafruit</span> </a> </lite-youtube></p> </div> </section> <section id="technical-details" class="prod-accordion-content prod-accordion-content-technical-details mobile-text-wrapper" aria-labelledby="tab-technical-details-heading"> <div class="tab-heading-row"> <h2 id="tab-technical-details-heading"> Technical Details </h2> </div> <div id="tab-technical-details-content" class="panel-collapse collapse in"> <p><strong>Specifications</strong></p><ul><li>Range: 0~150mm / 6"</li><li>Accuracy: ±0.2mm / ±0.01"</li><li>Resolution: 0.1mm / 0.01"</li><li>Repeatability: 0.1mm / 0.01"</li><li>Maximum measuring speed: 1.5mm / sec, 60" / sec</li><li>Power: When light is over 200 lux, the solar panel will activate.
