APPARATUS FOR MEASUREMENT OF WATER CONDITIONS IN A WATERMATTRESS Abstract of the Disclosure A method and apparatus for measuring water temperature in a waterbed are disclosed, the method including the steps of intro- ducing a sensing stem of a temperature measuring instrument into a water-filled mattress through a closure member positioned in the filler spout and securing the closure member and the temper- ature measuring instrument in sealing relationship to the spout to form a blunt-ended cap therefor. The apparatus of this inven- tion includes a cylindrical stopper that fits closely around an inside wall of the filler spout, a quantitative measuring instru- ment which includes a sensing stem and a crystal fitting over the end of the stopper and the filler spout for observing the measure- ments sensed by the instrument, and an annular hold-down member that runs around the crystal and the filler spout to secure the stopper in sealing relationship therewith.
