Měřič množství ozonu Sander univerzální

 The redox meter switches an ozone generator on when it
is below the desired value, and will switch it off when this
set value is reached. This gives you control over the
ozone dosage to the water and is a essential element in
the system. The redox meters come with calibrated
electrode (sensor) which should be replaced every 2
years. There are 2 models available: a universal model
with a 230V plug outlet that will be switched on/off, and a
special Sander model that keeps supplying current to the
generator but will deactivate ozone dosing.
