Water with value - Water sampling station PM 01

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 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.

The following function elements and accessories are already pre-assembled on the sampling station and/or contained in the scope of supply: strainer, needle valve, tubing with overflow and gas separator, potential-compensating pin, swing-out pipe for taking the sample water, flow rate monitor to switch off the controller functions when there is a shortage of water, balls for the electrode cleaning, connection cable for all sensors as well as a set of calibrations fluids for the sensors.
