ABSTRACT:
A reversing thermometer frame adapted to be clamped to a water sampler and lowered to a predetermined depth in a body of water. The frame has a base coupled to a case containing one or more of the reversing thermometers. The thermometer case is rotatable through about 180.degree. and is biased by a torsion spring reacting between the case and the biase for rotation from a first position to a second position. A releasable latch reacts between the base and the case to latch the latter in its first position against the bias of the spring. The thermometer case is open at one end for the insertion and removal of thermometers. At the open end of the case is a closure that is linearly and rotatably movable relative to the case so as selectively to close and open the open end of the case. The connection between the case and the closure is such that the latter must move linearly a predetermined distance relative to the case before it can be rotated, thereby preventing inadvertent loss of the thermometers.
