But what if its a top-quality brand, made in America, Switzerland, or Japan? And even comes with the box?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 very likely isnt, and either way you wont knowwhich defeats the entire 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 your measurement results and you have a penchant for significant uncertaintyor else are prepared to undertake the calibration yourself. But if you need to rely on the accuracy and precision of measurementsa fact that seems to be the foundation of the whole enterprisethen you must have confidence in them.

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 and precision: within ±. 0005 for the first 2-1/2 revs and ±. 001 for the rest of the measuring range; and repeatability and hysteresis within ±. While a new dial indicator. Be this accurate, it might not be, and it certainly isnt. I try to keep a variety of indicatorsincluding something for everybodylisted for sale at all times, but it can be difficult and I dont always manage to keep up. But even if you dont see many indicators listed here dont think theyre gone.

If youre interested in this fine Starrett indicator, consider looking at the other fine American-made Federal indicators for sale. If you are interested and there aren't any for sale, just inquire: I have plenty. For some reason Federals get less respect here than Starretts.

25-441 dial indicator with jeweled bearings, made in USA. New condition; better-than-new performance, because this indicator has been calibrated to a standard twice as acc urate and precise as a factory-new Starrett. Even the new indicators I sell undergo a thorough and meticulous inspection and precision calibration, so that I can stand behind the guarantee that its in perfect working condition and operating flawlessly. Plunge action is as youd expect from a perfectly functioning Starrett indicator: smooth, crisp, and responsive, with the lighter spring rate characteristic of this classic Starrett model.
The 25-441 is an AGD Group 2 gauge, with 2 dial diameter and 3/8 stem diameter. In case you were curious: the AGD (American Gage Design) protocol, for the purpose of standardization, specifies many of a dial-indicator's characteristics, among them the dial diameter (Group 1 is 1-1/2; Group 2 is 2; and so on, up to Group 4), a stem diameter of 3/8, and yellow dials for metric indicators. Non-AGD indicators (typically meant for the international market) usually have 8mm stems, though you can find special-purpose indicators that otherwise conform to AGD but have a variety of stem diameters. Mounting via the stem is the most common and practical method, so this detail can be very important. Note that you can use an easily acquired sleeve/bushing adapter to mount the smaller 8mm stem in the 3/8 holder found on most Noga-style stands, though not vice versa.The 25-441 features a continuous-reading dial to 100 (050100) with. 001 graduations and rev counter. 100 per rev for a measuring range of 01. 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 25-441, Im open to offers. Dial: Continuous-reading to 100 (050100).
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.
