Abstract

1431206 Electro-chemical analysis MINES DE POTASSE D'ALSACE SA 31 May 1973 (1 June 1972] 25975/73 Heading G1N A device I for measuring the amount of a chemical agent, such as halogenated antiseptic agents needed to sterilize water, in aqueous solutions includes an envelope having one of its ends closed by an electrically insulating material part, Fig. 1 (not shown) spacedly supporting reference electrode 3 and measuring electrode 4. Electrode 3 may be a Ag or Cu wire whereas electrode 4 is a spiral Pt or Au wire or perforated cylinder arranged concentrically within the helical reference electrode 3. The reference electrode may be in the measuring electrode. Leads connected to the electrodes pass through the opposite end of the envelope to measuring and/or agent controlling apparatus. In use a valve unit 12 provided with a small ball having a frusto-conical bore through it and turnable by key 13 is fitted to a side connection 11 of main pipe 10. The key is turned as shown and device 1 passed through the bore until electrodes 3, 4 are positioned as shown. Valve unit 12 is provided with a sealing joint 14 to prevent escape of water past device 1 when the valve is opened. The positioning on an arrangement of the electrodes as shown in the main liquid current produces an automatic cleaning thereof.
