【考案の詳細な説明】
本考案は、電流測定法を用いて次亜塩素酸ソーダの濃度
を測定する次亜塩素酸ソーダ測定装置に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a sodium hypochlorite measuring device that measures the concentration of sodium hypochlorite using an amperometric method.
次亜塩素酸ソーダの製造時に釦いては次亜塩素酸ソーダ
中を電解装置のもｔ′Ｌ電流が流れている。During the production of sodium hypochlorite, a t'L current flows through the sodium hypochlorite of the electrolyzer.
従来の装置でこの状態の次亜塩素酸ソーダの濃度を測定
しようとすると、もれ電流のため測定誤差が生ずる。If a conventional device attempts to measure the concentration of sodium hypochlorite in this state, a measurement error will occur due to leakage current.
筐た、従来の装置においては、電極の洗浄が面倒である
という問題や、電極に加わる同相ノイズに弱いという問
題がある。However, in conventional devices, there are problems in that cleaning the electrodes is troublesome and that they are susceptible to common-mode noise applied to the electrodes.
本考案の目的は、上記問題点を解決し、測定誤差が小さ
く洗浄が容易な次亜塩素酸ソーダ測定装置を提供するこ
とにある。An object of the present invention is to solve the above problems and provide a sodium hypochlorite measuring device that has small measurement errors and is easy to clean.
以下図面を用いて本考案を詳細に説明する。The present invention will be explained in detail below using the drawings.
図は本考案装置の一実施例を示す構成図である。The figure is a configuration diagram showing an embodiment of the device of the present invention.
図において、１は環状の指示極、２，３は指示極１の両
側に配置された環状の対極、４は指示極１および対極２
，３が内壁に固定された筒状の絶縁体である。In the figure, 1 is an annular indicator electrode, 2 and 3 are annular counter electrodes arranged on both sides of indicator electrode 1, and 4 is indicator electrode 1 and counter electrode 2.
, 3 is a cylindrical insulator fixed to the inner wall.
指示極１は白金で構成され、対極２゜３は白金又は塩化
銀で構成されている。The indicator electrode 1 is made of platinum, and the counter electrode 2.3 is made of platinum or silver chloride.
絶縁体４は塩化ビニール等で構成されている。The insulator 4 is made of vinyl chloride or the like.
また、対極２と対極３は短絡され、接地されている ５
は指示極１と対極２，３との間に一定電圧（指示極１を

指示極１・対極２，３間に流れる電流を検出する電流計
である。In addition, counter electrode 2 and counter electrode 3 are short-circuited and grounded.
is a power supply that applies a constant voltage between the indicator electrode 1 and the counter electrodes 2 and 3 (about -1.0 V when the indicator electrode 1 is made of platinum and the counter electrodes 2 and 3 are made of silver chloride 2 and 3); Reference numeral 6 denotes an ammeter that detects the current flowing between the indicator electrode 1 and the counter electrodes 2 and 3 by the power source 5.
この電流計６の指示値は１、従来装置と同様な原理から
、次亜塩素酸ソーダの濃度に対応している。The indicated value of this ammeter 6 is 1, which corresponds to the concentration of sodium hypochlorite based on the same principle as the conventional device.
この装置にかいては、対極２，３の電位が等しくなるよ
うに構成されているから、次亜塩素酸ソーダの製造時の
雰囲気であっても、円筒状絶縁体４内を電解装置のもれ
電流が流れることがない。Since this device is constructed so that the potentials of the counter electrodes 2 and 3 are equal, even in the atmosphere during the production of sodium hypochlorite, the inside of the cylindrical insulator 4 is the same as that of the electrolytic device. No current will flow.
したがって、もれ電流に起因する測定誤差は生じない。Therefore, measurement errors due to leakage current do not occur.
斗た、電極１〜３が全て環状であり、しかも絶縁体４内
に同軸的に配置されているため、洗浄が容易である。In addition, since the electrodes 1 to 3 are all annular and are arranged coaxially within the insulator 4, cleaning is easy.
！た、対極２，３が接地されているため、同相ノイズに
よる測定誤差も生じない。! Furthermore, since the counter electrodes 2 and 3 are grounded, measurement errors due to common mode noise do not occur.
なお、上記の説明に釦いては、中央に指示極１を配置し
、その両側には対極を設けたものを示したが、その逆で
あっても良い。In the above description, a button is shown in which the indicator electrode 1 is arranged in the center and opposite electrodes are provided on both sides, but the opposite may be used.
以上説明したように１本考案によれば、測定誤差が小さ
く洗浄が容易な次亜塩素酸ソーダ測定装置を実現できる
。As explained above, according to the present invention, it is possible to realize a sodium hypochlorite measuring device that has small measurement errors and is easy to clean.
