Rugged precision instruments for measuring or determining tilt and is designed for long life and easy handling. Angles are read directly to one minute, 30 seconds, 20 seconds...depending upon model. The lower 6" x 1-1/2" base plate and the compensating screw is suitable for use on shafts, propellers, wing surfaces, machine tools, test tables, production fixtures, and more. The lower base plate and compensating screw may be removed permitting the fixed base to be used in contact with the working or reference surface. All working parts are effectively enclosed - dust tight case assuring abrasion free contact between the accurately ground arc and worm gear. The lower base plate provides in addition to flat pads, a shallow V with clearance cut and center relief. Complete with instructions and storage case.

The WK pendulum clinometer is easy to use and invaluable for use in awkward locations. Simple to use, yet accurate to suit many applications. Features extended vernier with magnifier which makes reading easy. The instrument incorporates a drum locking device which enables the operator to secure the indication of angle before the clinometer is removed from the surface.

W-K's precision optical clinometers have a 360 degree operating range reading to either 10 seconds (Model 23-1190) or to 1 second (Model 23-1195). They are used for calibration, alignment, machine setting, boresighting, fire control alignment, and inspection when the tightest tolerances are expected and required. They can also be used as a circular worktable in either horizontal or vertical planes when fitted with the optional Warren-Knight Worktable and Supporting Base. When used in conjunction with the W-K Mirror Reflector and W-K Autocollimator, these clinometers can be used to precisely measure angles in any plane. The optical reading system and the bubble unit can be illuminated by daylight or by a low-voltage lamp system. When the utmost precision is required use only W-K's optical clinometers.

This 180 degree Clinometer can be instantly adjusted through 3 degrees to a base, then angles can be measured directly in relation to this base and read to 5 minutes. The arc is engine divided to single degrees. 90-0-90 degrees. Vernier arm may be moved through the full graduation range and locked at any point. Measures 7.25" x 2". Height is 5".

This clinometer precisely measures angles from a horizontal plane and is divided to single degrees over a 140 degree range. The level vial is graduated to 60 seconds per 2mm. A right angled precision ground cross vial is mounted on the base. A movable vernier arm clamps at any position and allows reading of the angle to either one or five minutes depending on the model. They are ideal for leveling and aligning machinery, small platforms and fixtures. Radius arc 2.25". Vernier arm 4.5". With case.

Measures angles quickly and accurately to 15 minutes. Engine divided from 50-0-60 degrees. The level vial adjusts easily to a reference base of plus or minus 6 degrees. The clinometer is favored by engineers, inspectors, pipe and steel fabricators, plumbers and electricians. Manufactured of corrosion-resisting metal and is shaped for maximum part protection. Measures: 1.25" wide x 6" long x 4.75" high. Weight 17 oz. With case.

Measures inclination or slope with a range of -5 to +10 degrees, reading by the vernier to 30 seconds. The arc is divided every 15 minutes and numbered every 5 degrees from -13 to +18 degrees. The attached magnifier can be positioned to read the vernier over the full range of the graduated arc. A 60" per 2mm grad. level vial is mounted on the vernier arm. Overall height is 3.25 inches, the base is 5" long, 1" wide. With case.

A four-way precision instrument that measures angles directly between any two planes or any number of planes, such as setting a detachable blade type propeller on an airplane. Snug fitting circles are tooled to close tolerances that minimize the error and play found in other protractors. The circle and plate vial are accurate to 45 minutes per 2mm. The vernier reads to six minutes and can be set to read angles at any position. Measures 7.25" x 7.25".

Capable of providing 360^0's  of range, this unit offers accuracy of 0.05⁰ .  This unit is amazingly versatile and priced affordably making it the low cost solution to quick and painless angle measurement.   The available RS-232 output port makes this unit the easy to integrate. Also available with a magnetic base.   

This Precision Quadrant Level was originally made for the Navy and is graduated to give a direct reading to 10 seconds with a range of -2 to +110 degrees. The quick accurate leveling of the 20 second per 2mm level vial is accomplished by means of a clamp and slow motion tangent screw. This clinometer has been used in shipbuilding yards to calibrate fire control directors and most other alignment applications. Arc radius 6-7/8". Base 5" x 12". Complete with case.

Model 23-4000 Series Micrometer Drum Block Levels are ideal for inspection activities and for shop applications. Block levels have gained widespread acceptance in shipbuilding, aircraft development, and maintenance activities as they provide a rapid means of accurately and reliably determining angles of inclination with simple adjustment. Range +3 degrees to -2 degrees. Measures 8" x 2" x 3.75". 4 lbs. With case.

Level This level provides fast, precise, accurate leveling of any flat surface, establishing a true horizontal plane within 1/4 second of arc or better. The coincidence or split-bubble level is conveniently viewed from the right angled eyepiece. The eyepiece can be mounted for sighting in, at almost any angle from 0 to 90 degrees. Mounting holes are provided for permanent mounting to fixtures. With case.
