Wild T2 Universal Theodolite

 

The well-known Wild T2 Universal Theodolite is ideally suited for almost every type of survey task. In addition to its high accuracy, with direct reading, to single seconds, it is simple to handle, has a well-illuminated optical and reading system and can be used with a large variety of accessories and attachments.

The optics are sufficiently good to allow observing to normal targets up to 12 miles (20 km) away and, under favorable conditions, for pointing to the Pole Star to be made in the late afternoon. Circle readings, are made through one eyepiece, an inverter knob bringing the required circle image into the field of view. Coincidence setting provides a direct meaning of the two diametrically-opposite circle positions. The single second graduations and the general quality of the T2, with its all steel construction offering addition-al stability, make it a real "Universal" theodolite widely used for triangulations up to 3rd arid even 2nd order limits, precise traversing, subtense measurements, astronomical observations, tacheometry, engineering work of all types, cadastral lay-outs, staking-out straights and curves, mining surveys and special industrial purposes, for which the special inter- changeable GOA autocollimation eyepiece is most useful.

The T2-E is identical to the T2, apart from the upright telescope image and the T210 is another Variation of the instrument which, in this ease, has no vertical circle, being used for tasks where the T2's accuracy is required but without vertical angles.

All models of the T2 are made so that the instrument can be removed from its tribrach and replaced by a target or subtense bar, without disturbing the centering. lf required, a special tribrach without built-in optical plummet, is available and another special tribrach fitted with a ball-centering device enables the T2 to be set up on an observation pillar in an embedded centering socket (a pillar bolt).
