similar to considered inclinometers (Fig.5.3). Unlike
inclinometers types ISH and IK device provides the work in
drilling tool and in a cased wells where the diameter of the passage
opening not less than 30 mm. UMI-25 device can be operated with
single-and two-core cable.

Inclinometers IT-200 and I-7 used to study deep and
ultradeep wells. By design they are similar types of inclinometers
ISH, IK and UMI.
