The Federal I got from you is more accurate than the Interapid I have. You calibrating them makes all the difference.

Mind, it further confirms all you state in your descriptions as true. This indicator is absolutely gorgeous. Thank you for switching out the plate for the lug. Put it into action within a couple of hours.

25-441 dial indicator with jeweled bearings, made in USA. New condition; better-than-new performancebecause this indicator has been calibrated to a standard twice as acc urate and precise as a factory-new Starrett. Plunge action is as youd expect from a perfectly functioning Starrett indicator: smooth, crisp, and responsive, with the lower indicating force characteristic of this classic Starrett model. The 25-441J is an AGD Group 2 gauge, with 2 dial diameter and 3/8 stem diameter.

Features a continuous-reading dial to 100 (050100) with. 001 graduations and rev counter.

100 per rev for a measuring range of 01. This indicator has a flat back; I have another 25-441 listed with a lug back. The classic American-made Starrett indicator, here guaranteed to work flawlessly and to a standard twice as accurate and precise as a new one. If you can beat this deal on a new, calibrated, guaranteed 25-441J, make an offer. In case you were curious: the AGD (American Gage Design) protocol, developed for the purpose of standardization among gages, specifies many of a dial-indicator's characteristics, including the dial diameter Group 1 are approx.

2; and so on, up to Group 4, at 3-1/2, a stem diameter of 3/8; 4-48 threading on contact points; and yellow dials for metric indicators, among other things. Non-AGD indicators (DIN- or JIS-conforming and typically meant for the international market) usually have 8mm stems and outer dimensions that generally correspond with AGD indicatorsthough you can find special-purpose indicators that otherwise conform to AGD but have a variety of stem diameters.

I have some Starrett AGD2 indicators with 7mm stems, if anyone is looking for this rather unusual size. Mounting via the stem is the most common, practical method, so stem diameter is important.

Note that some indicator holders can accommodate both stem diameters, but if not you can use an easily acquired sleeve-bushing adapter to mount the smaller 8mm stem in a 3/8 holder, though not vice versa. Dial: Continuous-reading to 100 (050100). Other: Calibrated to standard twice as accurate and precise as new. An important note to buyers: cold temperatures can and will adversely affect the functioning of precision gages, including dial indicators.

To be safe, please allow your indicator(s) to acclimatize fully to room/shop temperature before actuating plunger/lever. If you have any questions at all, dont hesitate to contact me. Ive tried to take photos showing the item as a whole and in detail from every angle; but if youd like to see something in better detail or if Ive left out something that you want to see, just let me know. Are included only if shown and/or described in listing. Please inform me if you do.

But what if its a top-quality brand, made in the U. That's all well and good, but it doesnt mean a thing in terms of indicator performance. Though it might be indicating with sufficient accuracy and precision, it just as likely isntand either way you wont know. That significant uncertainty defeats the purpose of using precision gages. It was so far out of calibration as to be useless, and yet most sellers are listing untested indicators just like this and calling them perfect.

This doesnt present a problem if youre unconcerned about the reliability of your measurements and you have a penchant for significant uncertainty, or else are prepared to undertake the calibration yourself. But what if its an Interapid? All the indicators I sell are mechanically and functionally new. I can make and guarantee this claim because every indicator I sell undergoes an extremely thorough and meticulous servicing, including. Cleaning of all parts in ultrasonic cleaner and/or by hand when necessary. Inspection of all parts, for wear and damage, and of the indicator as a whole, for smooth and correct function. Refurbishing and replacement of worn or problematic parts when necessary. Precision tuning and calibration, so that every indicator is verified and guaranteed to be working perfectly and indicating to the very same standard of accuracy and. Precision as new indicator, and in many cases.

0005 drop indicatorsto a standard twice as accurate and precise as new, guaranteed. I remain in some doubt as to whether most buyers recognize the benefits of this process for indicator function. Completely overhauling a gage confers manifold benefits, and it requires a major investment of time and labor. Aside from the obvious benefit of putting the indicator in the best possible condition (both cosmetic and functional) and ensuring that it performs perfectly now , it also ensures that the indicator will continue to function perfectly for as long as possible into the future.

Opening an indicator up and looking inside allows the technician (me) to discover any developing or potential problems and to nip them in the bud. Even if an indicator appears to be functioning correctly (which already presents problems of its own), if it hasnt undergone this type of servicing there may be problemsarising from dirt, accident, or abuselurking within that havent yet reached a critical point, but will. In this way, too, these are far more like new indicators than used ones. Gage was tested on a NIST-traceably calibrated gage tester that is graduated in 10 millionths. This provides the precision necessary for testing even tenths gages. Nowhere else will you find this kind of guaranteed quality at such a value. 001 indicators this means accuracy of ±. 002, respectively, and repeatability and hysteresis within. In contrast , I guarantee the gage to twice that accuracy: within ±.

0005 for the first 2-1/2 revs and ±. 001 for the rest of the measuring range. While a new dial indicator might be this accurate, it may not be, and it certainly isnt guaranteed.

A long-form report (which records the gages accuracy over its measuring range and provides a kind of map of the its accuracy) is not available with a new gage, even when you pay a lot more for a certificate but is available here at additional cost. I try to keep a variety of indicators listed for sale at all times, but it can be difficult and I dont always manage to keep up.

If you dont see many indicators listed for sale, dont think theyre all gone. I have a large inventory with a variety of brands including Starrett, Mitutoyo, Federal/Mahr Federal, Brown & Sharpe Bestest, Interapid, Compac, and more, in a wide range of types, graduations, measuring ranges, colors, prices, etc. Dont hesitate to contact me if youre looking for something in particular or to ask for recommendations. If you have any questions about this indicator, other indicators, or indicators in general, dont hesitate to contact me.
