Product Description:

The Model TC-II Cathetometer from Titan Tool Supply performs accurate, precise, non-contact measurements of both vertical displacement parameters and linear distances between two points, in areas which might be otherwise inaccessible to an indicator, scriber, or other mechanical checking device due to distance or combinations of blended curves, as well as in other applications where remote viewing may be preferable or required.

Design of the Model TC-II Cathetometer incorporates an industrial-grade micro telescope together with a simple “crosshair” reticle, the latter of which is mounted in the eyepiece. The reticle itself features vertical and horizontal divisions, as well as two concentric circles and an adjustable focal length range from 4” to infinity. The Model TC-II maybe be attached to any standard American or Foreign Height Gauge 18” or larger via its 1/4” X 1/2” holding bar, and in place of an indicator or scriber attachment. As the Cathetometer weighs less than one pound, it can level perfectly on even the lightest Height Gauge.

Applications:

Non-contact linear distance and vertical displacement measurements

Liquid level measurements

Barometer calibrations

Instrumentation readouts of liquid column thermometers and manometers

Any applications where non-contact remote viewing may be preferable or required.

It is important never to change the cross hair reticle adjustment on the Cathetometer while the instrument is in use. Otherwise errors result.

Operating Procedure:

1. Attach Cathetometer to a Height Gauge.
2. Place Height Gauge on surface plate or any other level flat surface.
3. Looking through eyepiece, turn knurled knob by the eyepiece until the cross hair is in sharp focus.
4. Adjust height approximately for the Cathetometer to line up with the object to be checked.
5. Rotate knurled eyetube in front of Cathetometer until object is in sharp focus.
6. Readjust height with fine adjustment to bring starting point in line with cross hair of Cathetometer. The fine adjustment on the Cathetometer can also be used for this purpose as well as for leveling the instrument as it is provided with its own liquid level to use when necessary.
7. Having the Cathetometer lined up on the starting point, take a vernier reading on the Height Gauge beam. Move the Cathetometer on the vertical beam of the Height Gauge to the next point to be checked. Take a reading. subtract reading #1 from reading #2 and the distance between the two points is realized.
8. Continue further readings following the same procedure.
