Numerical temperature reading apparatus for spa, swimming pool and whirlpool

A fitting device for adapting a liquid temperature probe to a tub with a threaded outlet from outside to inside of said tub, said liquid temperature probe comprising a contact point for probing liquid temperature, an enveloping body and a cable for transmitting data, said fitting device comprising in combination:

• an elongated hollow body with first and second ends and a central body (34) with a fore end and an aft end, said first end including a dome to be directed towards said outlet, and further including a ring shaped extension of said central body around said dome, the space between said ring shaped extension and said dome defining a liquid circulation channel,
• said central body having, from the fore end to the aft end:
• first male threads for mounting (40), on said fore end, for adapting to said outlet,
• a central external portion comprising means for engaging said first male threads for mounting (40) into said outlet,
• threads on the aft end, and
• an internal chamber for receiving said enveloping body (46),
• said first end of said elongated hollow body being a closed end (27) and said second end being an open end (25), said closed end (27) comprising said dome (44) with the convex part oriented opposite to said central part and being adapted for contact with said liquid, said dome (44) receiving said contact point (47) in its concave part,
• a cap (28) comprising means for progressively engaging said threaded aft end, and simultaneously pushing against said enveloping body.
• a slit (57) for permitting the passing through of said cable,
• so that the passing of said cable through said slit and progressive engaging of said cap along said threaded aft end causes the pushing of said liquid temperature probe into intimate contact with said dome.
