Measuring & Control Equipment


The Lutz Jesco EASYPRO range of standard configuration water analysis stations allow continual measurement of the process water in public swimming pools, industrial plant and hot water installations up to 65 °C.  

The modular design of the water sampling station allows customisation to suit your exact needs. A flow controller ensures a constant flow of 30 l/h and leads the sample water to the measuring cell in the shortest possible time, to guarantee high measurement accuracy. 

The Topax controller mounted on each board allows for customisation of all inputs and outputs and complete control and analysis.  

  • Measurement of (free chlorine) Measuring range: max. 10.00 mg/l
  • Measuring of the total chlorine Measuring range: output 4 – 20 mA
  • Measuring the conductivity Measuring range: output 4 – 20 mA
  • Measuring the pH value Measuring range: pH value 0 – 14
  • Measuring of the Redox potential Measuring range: 0 – 1000 mV
  • Measuring the temperature Measuring range: 0 - 100 °C
  • Reading in the digital display
  • Warning via red LEDs, should measured values be outside nominal range
  • Control of the downstream dosing systems
  • Automatic recording of the measured values via separate software possible
  • Easy to assemble: The water sampling station can be unlocked and opened using the lock (right-hand side)
