Where punctual and rapid controls of water quality are necessary (swimming pools, aquariums, drinking water stations, etc.)

The pocket photometers MW10 and MW11, economic series, provide numerical results of free or total chlorine concentrations. Unlike analysis kits which provide an indication by comparison, MW photometers display a direct reading of chlorine concentration.
