I recently acquired the Mitutoyo 500-197-30 Advanced Onsite Sensor (AOS) Absolute Scale Digital Caliper and have been impressed with its precision and reliability. This digital caliper stands out for its advanced features and accuracy in measurements. Here's a detailed review based on my experience:Key Features:Advanced Onsite Sensor (AOS) Technology:The AOS technology in the Mitutoyo 500-197-30 ensures an enhanced measurement experience. It allows for quick and accurate measurements by eliminating the need to set the reference point each time the caliper is powered on.Absolute Scale System:The Absolute Scale System ensures that the caliper retains its zero-point origin, even after powering off. This feature eliminates the need to recalibrate the caliper, saving time and ensuring consistent accuracy.Large LCD Display:The large LCD display provides clear and easy-to-read measurements. The digital readout ensures precision in readings, and the screen is well-lit for visibility in various lighting conditions.Stainless Steel Construction:The caliper is constructed from high-quality stainless steel, ensuring durability and resistance to corrosion. This robust construction contributes to the longevity of the caliper, making it suitable for long-term use.Smooth Slider Movement:The slider movement is smooth and precise, allowing for easy and accurate measurements. The well-designed slider ensures that measurements can be taken smoothly without any play or deviation.Metric and Inch Conversion:The ability to easily switch between metric and inch units adds to the caliper's versatility, accommodating different measurement preferences and requirements.Thumb Roller for Fine Adjustment:The inclusion of a thumb roller allows for fine adjustments when measuring, providing users with precise control for accurate readings.Considerations:Battery Life:While the battery life is generally good, some users may prefer a longer-lasting battery for extended periods of use. However, the efficient power usage ensures that the battery life remains satisfactory for most applications.Protective Case Quality:The protective case provided with the caliper, while functional, may not be as durable or protective as some users might expect. Users should handle the case with care to ensure its longevity.Conclusion:In conclusion, the Mitutoyo 500-197-30 Advanced Onsite Sensor (AOS) Absolute Scale Digital Caliper delivers on its promise of precision and reliability. The advanced sensor technology, absolute scale system, large LCD display, and durable construction make it a valuable tool for precise measurements. I highly recommend the Mitutoyo 500-197-30 to professionals and enthusiasts who require accurate and consistent measurements in various applications.

er Mitutoyo 500-197-30 Digitaler ABS-AOS-Messschieber hat mich als Sportschütze voll überzeugt. Ich nutze ihn hauptsächlich, um Hülsen für das Wiederladen exakt zu vermessen, und kann sagen, dass dieses Werkzeug in puncto Präzision und Handhabung unschlagbar ist.Die digitale Anzeige ist klar und leicht ablesbar, was die Arbeit enorm erleichtert. Besonders die Absolut-Messung (ABS) ist ein großer Vorteil, da man sich nach dem Nullsetzen keine Sorgen mehr um versehentliches Verstellen machen muss. Der Messschieber bleibt einfach präzise, selbst nach mehrmaligem Ein- und Ausschalten.Was den Schießsport betrifft, ist die Genauigkeit bei der Vermessung von Hülsen entscheidend, um sicherzustellen, dass die Patronen gleichmäßig geladen werden. Mit dem Mitutoyo Messschieber konnte ich Hülsenlängen und -durchmesser zuverlässig und auf den Bruchteil eines Millimeters genau bestimmen. Dadurch habe ich eine bessere Kontrolle über das Wiederladen und letztlich eine konstantere Leistung auf dem Schießstand.Ein weiterer Pluspunkt ist die stabile Bauweise. Der Messschieber fühlt sich sehr hochwertig an, und die Führungsschiene läuft extrem leicht und gleichmäßig. Dank der robusten Konstruktion und der Schutzart IP67 ist das Gerät auch gegen Schmutz und Feuchtigkeit geschützt – ideal für den regelmäßigen Einsatz, auch unter nicht optimalen Bedingungen.Fazit: Der Mitutoyo 500-197-30 ist ein unverzichtbares Werkzeug für jeden, der im Schießsport präzise Hülsenmessungen benötigt. Absolute Empfehlung!

I had the cheaper models that keep giving varying readings every time I measure the length. Finally a quality vernier caliper that is awesome. Highly recommend. Thanks.😊

Ich wüsste jetzt nicht, wasman hier noch verbessern könnte. Hatte in meiner Lehre schon eine analoge Schieblehre von Mitutoyo (habe die immer noch) und nun mir diese hier gegönnt. Einfach klasse, das Teil!

Fake. Those of you who know how to spot a fake will see it.

Podria funcionar mejor? Es muy dificil. Tomas una medida y la tomas un montón de veces más y siempre da la misma medida.

Die Verarbeitungsqualität ist sehr gut und die Messschenkel sind voreingestellt absolut parallel - kein Nachjustieren nötig.Die Messtoleranzen werden voll und ganz erfüllt (gemessen mit Mitutoyo Einstellmaß).Kann ich empfehlen

Reading online, I came to the conclusion that this model seems to be the most copied one.And also reading the comments here that even when Amazon as seller some have received counterfeit ones but I took a chance and ordered Amazon as the seller and received a Genuine one.But be aware there are some pretty good counterfeits,when you receive yours google for the differences!

Es kam eine völlig andere Schieblehre an.

Works perfect better then all the crap i have been using before

These are genuine mitutoyo calipers, there's not really much more to say about them. They work perfectly, they measure perfectly, the battery lasts forever and the absolute measurement means you never need to zero the calipers.Yes, these are expensive, significantly more expensive than the 150mm version but that extra 50mm over a 'standard' caliper makes a big difference - many times I've maxed out a standard caliper, the 200mm range is well worth having.Whilst cheap digital calipers are generally very good, they can be a bit hit and miss. Measurements with cheap calipers are typically very good, but they don't always run smoothly or can have points where the measurement skips, the steel isn't as hard as quality calipers and the grind of the faces isn't as good. The Mitutoyos of course exhibit none of these issues, they are incredibly smooth across the entire range, the steel is exceptional and the grinding is perfect. It doesn't matter how fast you open/close the calipers, it will never miss a step, and zero is always exactly zero.This model is not coolant proof, so not good for machinists, but they are perfect for engineers working at a desk or clean environment. Mitutoyo do of course have the coolant proof/waterproof version for use in a machine shop.
