Standard Gage digital electronic bore gage with SPC output The newest models of Standard Gage digital electronic bore gages are manufactured in Switzerland by Tesa, the manufacturers of high-end Etalon and Interapid gages. These digital bore gages can be zero-set to a master for comparative readings and can also be used for absolute reading by presetting to a master, such as a setting ring. Setting rings are not included and must be purchased separately. The minimum hold feature will allow you to rock the gage head through the bore and the display will show the minimum bore size. The .00005" (1µm) digital indicator makes this both an inch and metric bore gage with SPC (RS-232) output. The gage and its accessories come in a sturdy carrying case.

Depth extensions |
 |  |  |  |
Bore gage depth can be specified when the gage is purchased. The depth extensions are available for bore gage model 2, 3, 4, 5 and 6. The depth which these bore gages can reach is called the "A" length and this length is available from 4" to 72". Be advised that bore gages with added depth extensions will not function properly in the horizontal position. The weight of the long rod will bend the barrel and sluggishness or jamming will result. If you need to use the bore gage in a horizontal position, let us know in advance so we can advise the manufacturer who will make some factory adjustments (allow extra time). |

About the digital indicator |
 |  |  |  |
The top lifting cap as well as the contact point on the indicator must only be hand-tightened. Using pliers applies too much torque on the spindle and you can imagine what that does to the movement inside. Only the manufacturer and authorized repair centers are allowed to open the digital indicator from the dial side. Otherwise, warranties are null and void. The instrument's accuracy and other specifications are only guaranteed when the instrument is used at 68°F and [the digital indicator] is mounted vertically, clamped by its stem. manufacturer's notes paraphrased |
