Radioopaque Radiology (X-Ray) Rulers Ruler graduations register clearly on an x-ray film. The
rulers are 130 cm long by 38 mm wide, made of brass, nickel plated, and precisely
engraved, then filled with special x-ray blocking paint. The finished scales are
encased in clear PVC for protection and stiffness. A 1/4" hole through PVC and
brass above the 130 cm mark is provided for hanging when not in use. Placed next to
the object being x-rayed, they make an excellent measurement tool for any radiology
department. To order, call us at 708-449-5700 or e-mail us at email@example.com
