Gage Type
           
   Your choices are...         
   Comparator       Mechanical comparators, electronic comparators, or appliers and pneumatic or air comparators are gaging devices for comparative measurements where the linear movement of a precision spindle is amplified and displayed on a dial / analog amplifier, column, or digital display.  Mechanical comparators have sophisticated, low friction mechanism, better discrimination (~0.00001"), and lower range (~+/- 0.0005") compared to indicators.  Comparators have a higher level of precision and less span error compared to conventional dial or digital indicators.  The level or precision is sufficient for measurement of high precision or ground parts and for the calibration of other gages. 
   Gage Set       Gage sets include several gages and accessories packaged into a kit, usually in a case with adjusting tools. Tool kits sometimes contain alternate extensions and contact tips, holders, bases, or standards. 
   Gaging System / Station       Gaging systems or stations are larger, more complex units for large-scale gaging. They are usually available in bench top or floor mounted configurations. These devices may consist of several gages, fixtures, or other components for holding or manipulating parts during inspection.  Typically, systems or stations have specialized gaging or inspection systems customized for particular OEM application.  Air gaging stations, gear testing systems, form gaging systems, tire profiling systems, and universal gaging systems are example of these types of products. 
   Indicator       Indicators are gaging devices for comparative measurements where the linear movement of a spindle or plunger is amplified and displayed on a dial, column or digital display.  Typically, indicators have a lower discrimination (~0.001" to 0.0001") and greater range (~+/- 1.000" to +/- 0.050" total) compared to comparators.  The level or precision is sufficient for measurement of precision ground parts and for the calibration of other gages. 
   Test Indicator       Test indicators have the lowest discrimination when compared with indicators and comparators. Test indicators used mainly for set up and comparative production part checking.  Test indicators often use a cantilevered stylus or level style probe that facilitates inspection of hard to reach part features, but results in high cosine errors.  A cosine error of 0.0006" may result over a travel range of 0.010".  Test indicators are not considered absolute measuring instruments, but comparative tools for checking components against standard or zeroing-out setups. 
   Other       Other unlisted, specialized, or proprietary indicator, comparator, or test indicator types.

   Gaging Technology       
   Your choices are...         
   Air / Pneumatic       Gages or gaging systems use the changes in flow or pressure in air nozzles or inlets internally located in air plugs, probes, rings or snaps or other pneumatic gages. Pneumatic comparators, digital readouts, analog amplifiers, columns or flowmeter / rotameter tubes are used to display air gaging dimensional data. 
   Electronic       Electronic gages use LVDT, capacitance, inductive or other electronic probes to sense the distance or displacement of a contact or stylus. Mechanical gages such as micrometers, plug gages, and snap gages may employ an integral electronic probe in addition to the mechanical gaging elements. 
   Mechanical       Mechanical gages use comparison or the physical movement and displacement of a gaging element (e.g., spindle, slide, stem) to determine the dimensions of a part or feature. Micrometers, calipers, indicators, plug gages, ring gages or snap gages are examples of mechanical gages. 
   Other       Other unlisted, specialized, or proprietary technology types.

Measurement Scale / Units
   Units:       
   Your choices are...         
   English       Gages and gaging systems are based on the English system of measurement (e.g., inches). 
   Metric       Gages and gaging systems are based on the metric system of measurement (e.g., centimeters, millimeters). 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Display:       
   Your choices are...         
   Dial / Analog / Direct Reading Scale       Devices include dial displays, column/bargraphs, and direct reading scales. Dial displays use a pointer or needle mounted in a graduated, disc dial. The dial provides an indication of dimension or position around or from a zero reference point with dial graduations or styles, such as 10-0-10, 45-0-45, 4-0-4 or 50-0-50. Column and bar graph displays provide a graphical presentation of dimensional data. Direct reading graduated scales have rulings or graduations engraved or printed onto a linear, disc, or drum surface that provides a direct indication of the gaged dimension. Vernier scales provide additional amplification or an increased level of precision (e.g., thousandths).  
   Digital Display       Digital display types present metrology data in numeric or alphanumeric form. Micrometers, calipers, and indicators are available with digital displays. Gages with digital displays often have data output capabilities using serial or other formats.  Digital readouts are a precision type of digital display integrated into dimensional gages or systems.

Mounting / Features
   Mounting / Loading:       
   Your choices are...         
   Automatic / Inline       The part is automatically presented to the gage and measured without operator intervention. Inline devices are automatic gages used in a production line. In semi-automatic systems, a part is presented manually to the gage or gaging system and then measured automatically. 
   Benchtop / Floor       Devices are benchtop, table-based or floor mounted gages or instrument where a part is both manually loaded and measured. 
   Handheld / Portable       Devices can be operated while being held in the hand and/or are portable. 
   Machine Mounted       Gages are mounted on or within a machine tool or equipment for tool setup or travel measurement. Test indicators, dial indicators and micrometer heads are examples of gages that are often machine mounted.
