Quick and precise measurement of important water treatment parameters with the Siemens Photometer P15 plus, now with a measured value memory and real-time clock

The new version of the Photometer P15 plus from Siemens Water Technologies has a measured value memory and a real-time clock. It can store the values of up to 16 of the most important water treatment quality parameters, together with their times of measurement. Factors that could impair measurement – such as excess turbidity of the water sample – are automatically detected and displayed. The illuminated display makes the device easy to use, even under difficult conditions. Parameters such as pH value, acid capacity, free and total chlorine content, chlorine dioxide, bromine, ozone and cyanuric acid can be measured quickly, easily and precisely.

The portable photometer is compact, ergonomically designed, and powered by a 9 volt battery. The cell compartment is hermetically sealed to prevent water penetrating into the electronic components. The P15 plus has a software-supported calibration facility, which qualifies it for use as a testing instrument. The scope of supply includes 400 reaction tablets. Siemens Water Technologies also provides liquid reagents on request.

The photometer is very easy to use. The sample tube is first filled with the water to be tested, and placed in the cell compartment. The device is zeroed simply by pressing a button. The sample tube is then removed, and a measuring reagent added to the sample water. After color has developed in the sample, the tube is returned to the cell compartment. Pressing the button once more displays the values of the constituents and other quality parameters. The photometer has a count-down function for determining parameters that require a certain reaction time. It emits an acoustic signal as soon as the displayed value is valid and can be recorded.
