The Milwaukee MW10 photometer is compact and easy to use, has a modern design, and measures free chlorine (0.00 to 2.50 mg/L). Chlorine is the most commonly used water disinfectant. Applications vary from the treatment of drinking water and wastewater to pool and spa sanitization, from food processing to sterilization.

The main advantage of the MW10 is 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.

The MW10 works 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. The photometer measure this coloration. When a light beam passes through the colored sample, energy with a specific wavelength is absorbed by the test substance. The photometer determines the coloration of the sample by measuring the transmission or absorption of light of this wavelength. The photometer then uses a microprocessor to calculate the concentration and displays the result.

The field of application is 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 the MW10.
