Latest Answers for the Product
The Mitutoyo 293-340-30 Digital Micrometer uses a standard SR44 battery, and according to the manufacturer's product description, it should last around 2.4 years with normal use.
So, you shouldn't have to worry about changing the battery too often, especially if you're using it occasionally or for short periods.
From what we've found, folks are generally happy with how long the battery lasts. They appreciate not having to swap it out frequently, which makes things all the more convenient.
Plus, there's a helpful low-battery warning feature so you don't get caught by surprise when it's time for a change. This is especially handy for professionals who count on it for precise work.
Keep in mind, though, that the actual battery life might vary depending on temperature and how often you're using it. If you're using it a lot or in colder conditions, the battery might run out a bit sooner.
That being said, most people we've heard from think the battery life is just fine for what they need.
Overall, it seems like the Mitutoyo 293-340-30 should be a solid choice if you need a digital micrometer with reliable battery performance—just make sure to have a spare on hand if you're worried about running out of juice.
So, about the Mitutoyo 293-340-30 Digital Micrometer, it doesn't actually come with a calibration standard in the box. The manufacturer highlights that having it properly calibrated is super important to get accurate readings.
Usually, you'd need an external reference to zero it out before taking any measurements, and that's something you'd have to find separately.
Our research shows that some folks have run into issues with calibration, especially when trying to zero the device. It seems like getting a consistent zero can be a bit tricky, and a few have reported that even after several attempts, keeping it calibrated can still be challenging.
If you're having trouble, checking out the manual for the proper steps is a good start. Also, make sure the device itself is functioning right—things like debris or damage to the carbide-tipped faces or ratchet mechanism can throw things off.
And if you're still stuck, reaching out to Mitutoyo customer support might be your best bet. They might have some advice or be able to help, especially if it turns out there's something off with your specific unit.
While Mitutoyo tools usually have a great reputation, a few quirks might crop up occasionally.
In short, while it doesn't come with a calibration standard, keeping it in check with the right procedures and maybe a bit of extra support should make it work well for you.
The Mitutoyo 293-340-30 Digital Micrometer is known for its impressive accuracy, particularly in professional settings like aerospace machining, where precision is non-negotiable. Our research indicates this micrometer has a resolution of 0.00005 inches (or 0.001 mm) with an accuracy of +/-0.00005 inches. If you need exact measurements, it's definitely up to the task.
One handy feature is its dual-readout display, letting you easily switch between inches and metric units. This can be really useful if you often find yourself working with different measurement systems.
As for build quality, it's quite robust, designed to withstand the demands of tough work environments. It has a ratchet stop mechanism for consistent pressure, which is great for accurate and repeatable measurements.
Plus, with an IP65 rating, it's resistant to dust and water, so it's a solid choice if you’re working in a workshop where those could be issues.
There are a couple of minor things to keep in mind. Our research mentions that it doesn't come with a standard bar for calibration, which might be important for long-term accuracy. Also, it doesn't have an on/off button, which some find inconvenient; however, it does have an auto-off feature to save battery when not in use.
While it might be pricier than some alternatives, many find its performance and durability justify the cost. If you’re looking for a reliable tool for precise measurements, the Mitutoyo 293-340-30 could be the way to go.
