J.A. King / J.A. King / NC Measurements and ST Comparators

Standard Features:
Anodized, high-precision measuring stage with 4" x 8" or 4" x 12" travel. Readings are via .00005"/.001mm precision glass scales. Cross travel via a threadless ball bearing, fine adjust and quick release on x axis. Vertical travel, (focus-4"), via centrally located handwheel. Oversize ground bearings for smooth, accurate focus.

All controls are easy to reach and read. Rotating glass screen with digital readout protractor, readings via "Q" axis of DRO. Frosted glass screen with 30 and 90 degree cross lines and adjustable duplex fiber-optic surface illumination. Long-life Tungsten-Halogen bulbs for both profile and surface illumination. 3-position lens turret for quick change of magnification. Units with optional fiber-optic edge sensor have NEW flip-up arm for edge-sensor cable. The "4600" series comparator is available with your choice of three digital readout systems as shown below.

Digital Readouts:

	Quadra-Chek 221 and 221E These powerful digital readouts provide fast geometric computations in a simple, easy to use format. Functions include point, line, circle, distance, angle, skew alignment and Measure Magic. Other features include Inch/MM, Cartesian/Polar, nearest/farthest distance, complimentary angles, serial and parallel ports and 200-feature memory. Large, high contrast LCD screen graphically displays measurement features and construction. Housing tilts backward or forward for best angle of operation. Model 221E includes fiber optic edge sensor.
	Standard Digital Readout The Standard digital readout features absolute/incremental, IN/MM conversion, random zeroing, RS232C output, linear error compensation and Q axis for digital screen protractor.
