ABSTRACT:
A probe or instrument to be moved through casing assemblies having ports therein at different levels selectively to take samples and/or measurements at these levels. The probe is an elongate body which is lowered through the casing assembly by a suitable cable. A stop on the body cooperates with a stop in the casing assembly at each level to position a port in the body in registry with a port in the casing at this level. A seal on the body is pressed against the adjacent casing assembly wall to isolate the registering ports from the interior of the casing at this time.
