5.0 Measuring Cells for free chlorine.
Working Temperature: 0 to 45 ° C.
Conductivity of water:> 10 μ S / cm
Max Working Pressure = 0.5 BAR
Output signal: 4- 20 mA current proportional to ppm reading
Power supply 12 Vdc ± 1 V
Life of electrolyte: about 3 months (or less if the concentration of chlorine is high)
Life membrane: about a year (but is highly dependent on water quality)
For the calibration, there must be a device to determine the content of free chlorine in accordance with the
method DPD (recommends the use of a photometric instrument).
The reading of chlorine is with reduced influence of pH changing (pH range 4 - 12).
