New Water Sampling Station

摘要

The water quality in modern swimming pools and waterworks is guaranteed thanks to automatic measuring and control systems. The water sampling station PM 01 developed by Lutz-Jesco (Germany) complies with German Standard DIN 19643 and serves to record and control the concentration parameters of the free chlorine, the pH value, the Redox-Potential, the temperature and also, optionally, the conductivity. The measurement of free chlorine is done on the basis of a potentiostatic measurement cell for residual chlorine, which requires a water flow rate of approx. 45 l/hr. Rotating balls thereby ensure a continuous electrode cleaning. The sensors used to measure the pH value, Redox-Potential and temperature are set depending on the application and are fitted in a see-through multi-function mounting block. A hydrostatic flow-through regulator of the water flow rate ensures a constant measuring condition. An automatic electric controller from the TOPAX range is in charge of regulating the water quality. The sampling station is available in many various models: the basic equipment is the potentiostatic 3-electrode sensor to measure the concentration of free chlorine, the further sensor mounting is completely flexible.
