                |  | The THV instrument 
                  fulfills the constantly increasing high quality requirements 
                  of industrial manufacturers for many applications. With a single 
                  measuring system, the checking of internal and external sizes 
                  can be accomplished easily and accurately. Basic gage calibration 
                  can also be achieved with this unit. |   
                | High 
                  accuracy is guaranteed by perfection in instrument construction, 
                  and the use of the Heidenhain or Sylvac measuring systems. The 
                  simplicity of the unit and its ease of use allows precise and 
                  quick performance of all measurements. The instrument can be 
                  used in a horizontal position, or can be rotated through 90 
                  degrees using the optional support stand. |   
              
             
               
                |  |  Shown here checking 
                  a ring gage, the THV is the ideal system for calibrating 
                  and inspecting many types of shop inspection tools, thus saving 
                  much expense on outside calibration laboratory costs.  In addition to 
                    gage calibration, the THV is ideal for the inspection of high 
                    precision machined parts.
