Possible causes
Measures for resolution
The chlorine measuring cell
displays too much with
respect to the DPD-1
measurement
May occur when using "water fining
agents". Chlorine-oxygen bonds are
contained in some of these agents which
react with chlorine to make chlorine dioxide,
thus distorting the measuring signal by
greater values
Refrain from dosing this agent. A change of water might be required.
The DPD-1 method displays
excessive chlorine content
to which the measuring cell
cannot be adjusted
Use of "organic chlorine". When using
organic chlorine products, cyanuric acid
accumulates in the swimming pool water.
Replace the water completely and use other chemicals for disinfection
