It has been developed an automatic electronic device whose operation We describe below.
La toma de muestra recibe una tensión de alimentación de 220 V AC 50 Hz. Estos son aplicados a un diferencial y un magnetotérmico, con el objeto de proteger el circuito diferencial a personas, y a su vez proteger los diferentes elementos en caso de fuga y el magnetotérmico posibles cortocircuitos.The sampling receives a voltage of 220 V AC power supply 50 Hz. These are applied to a differential and a circuit breaker, in order to protect the differential circuit to people, and in turn protect the different elements in case of leakage and the possible circuit breaker short circuits
La toma de muestras dispone de una toma de tensión de 220 V AC 16 A para la realización de tomar datos y mantenimiento (ordenador).The sampling has a voltage of 220 V AC 16 A for the realization of taking data and maintenance (computer).

- Mediante un SOFTWARE DE CONTROL se pone en marcha una bomba que aporta la muestra de biocida a analizar en un vaso. Un transmisor detector de la solución hace la primera medida del biocida residual en pH, medida 1 (diferencia de potencial mv_{1}).Through a CONTROL SOFTWARE you put a pump is in progress that provides the biocidal sample to be analyzed in a glass. A solution detector transmitter makes the first measurement of residual biocide in pH, measure 1 (difference of potential mv_ {1}).
Pasado un tiempo el software pone de nuevo en marcha la bomba, aspirando una cantidad de reactivo depositándola en el vaso de la muestra, realizando la segunda medida pH_{2}, medida 2 (diferencia de potencial mv_{2}). Esta medida aplicada al programa informático, mediante una ecuación interna refleja la cantidad de biocida residual de la muestra, aporta una lectura en p.p.m. guardándola en memoria el controlador.After a while the software puts back on start the pump, aspirating a quantity of reagent by depositing it in the sample vessel, making the second measurement pH2, measure 2 (potential difference mv_ {2}). This measure applied to the computer program, through an internal equation reflects the amount of residual biocide of the sample, provides a reading in p.p.m. keeping it in memory the controller.
La ecuación que se desarrolla es la siguiente:The equation that develops is the next:
- Toma muestra, medida de pH_{1} (milivoltios mv_{1})- Sample taken, measurement of pH1 (millivolts mv_ {1})
- Toma reactivo, medida de pH_{2} (milivoltios mv_{2})- Reagent sample, pH2 measurement (millivolts mv_ {2})
Por diferencia de pH_{1} (mv_{1}) - pH_{2} (mv_{2}) obtenemos la concentración del biocida residual en el agua en (p.p.m.)By difference of pH1 (mv1) - pH2 (mv_ {2}) we obtain the concentration of the residual biocide in the water in (p.p.m.)
pH_{1} (mv_{1}) - pH_{2} (mv_{2}) = f (p.p.m.)pH1 (mv_ {1}) - pH2 (mv_2) = f (p.p.m.)
