Abstract: An apparatus and method for measuring a range of small volumes of fluids to a high degree of precision, said apparatus including: a) a single reaction chamber (20); b) a piston (30) operable within said chamber to selectively and precisely vary the internal volume of said chamber; c) a first inlet (41) to said chamber in communication with one or more fluid sources of which a portion of a first fluid of said one or more fluids is adapted to be drawn into said chamber; d) at least one further inlet (43) including a second inlet to said chamber in communication with one or more fluid sources of which a portion of a second fluid of said one or more fluids is adapted to be drawn into said chamber; and e) a sealable outlet (45), wherein said piston is adapted to progressive draw said portion of a second fluid into said chamber until either accurare metering of a volume of said first or second portion of fluid is achived or a reaction involving said first and second portions in said chamber (such as a titration rea

Abstract: An electrically powered apparatus for generating a solute such as chlorine to sanitise a body of water such as a pool or spa, a by-product of such generation being an explosive gas such as hydrogen, said apparatus including: a) an electrolytic cell (1) adapted to operate in a substantially vertical orientation through a range of 45 degrees either side of the vertical; b) a water inlet (13) and outlet (14) both located at the lower end of said electrolytic cell (1); and c) a defined space (16) surrounding one or more electrodes (28) of said electrolytic cell (1), wherein, in, the event that water flow through said apparatus ceases and said electrolytic cell (1) continues to produce said explosive gas, said explosive gas will displace water in said defined space (16) until there is no water around said electrodes (28).
