Product Details
The 76-RH190M has precision telescope optics mounted on a solid-cast bronze horizontal axle which combine to produce a well-balanced instrument with feather-touch controls. The 76-RH190M is the undisputed "workhorse" of optical alignment, providing tremendous flexibility with substantial time and labor savings.The versatile Brunson 76-RH190M transit combines the traditional main telescope with a fixed-focus cross telescope mounted in the horizontal axis of the instrument. This second telescope is fixed at infinity focus to make collimation or autocollimation with another instrument or a mirror quick and easy. This capability means that the 76-RH190M can be quickly made perpendicular to an optical reference line. By simply shifting from the main eyepiece to the cross-axis eyepiece, an operator can establish or verify his/her position relative to the basic reference line in seconds. This effectively requires only one technician, where previously two were required.

Patented ball bearing mounts permit accurate sweeping of both horizontal and vertical planes. The 76-RH190M employs a 194-TM Coincidence level for precision leveling. The 194-TM has a 360-degree rotating turret to view the magnified bubble image from any position.Available with English, metric, or no micrometer. Measurements from the optical reference line are taken by using an optical micrometer mounted on the main telescope. The 76-RH190M comes standard with a model 190 Optical Micrometer. To order the transit with an English micrometer, see the 76-RH190. In event that you do not want either micrometer, order model number 76-RH.The 76-RH190M also comes with a model 509 Light Source, a carrying case, set of adjusting pins, instruction booklet, and plastic cover.
