The revolutionary new range of Milwaukee handy photometers are compact and easy to use, have a modern design, and measurePhosphate (MW12). Their main advantages are the small size, and the real simplicity when doing measurements on the spot. Within a few minutes you can get the required result on the LCD and the instrument directly displays the concentration of the specific component in ppm. The meter automatically turns off after 2 minutes in order to save the battery.They work exactly the same way as the other Milwaukee photometers.

When specific reagents are added, the water sample takes on a degree of coloration that is proportional to the concentration of the parameter being measured. Thephotometer measures this coloration. When a light beam passes through the coloured sample, energy with a specific wavelength is absorbed by the test substance. Thephotometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength. The photometer then uses a microprocessor tocalculate the concentration and displays the result.

The field of application is really wide including agriculture, drinking water analyses, aquariums, swimming pools or fish farms. As a result of this versatility and the affordable price it is undoubtedly worth using these products.
