Looking to create a very simple, small low power, light weight, circuit that can detect chlorine in water within a fixed range. The circuit would show green if both Total and Free fell within range and red if not. Free Available Chlorine Residual Total Chlorine Residual Total chlorine residual indicates how much chloramine residual is present, compared to free chlorine. This value should never exceed free available chlorine residual by more than 0.5 ppm. Superchlorination ensures chloramine levels remain at or below 0.5 ppm.

I have designed an ORP probe interface in the past that worked very well. Is ORP sensing good enough for your application? The current price and timescales are only place holders to allow me to communicate with you Best Regards Dave Lelievre
