Oxidation Reduction Potential (ORP) is a scale used to determine how strong the oxidizing process is in a liquid. In essence, the ORP level informs you on how much disinfecting (oxidizing) power is present. You can read more about ORP right here.
ORP Meter pool
ORP Meters are especially used by pool and spa owners who need to measure the chlorine level of their pool regularly. When we add chlorine (oxidizer) to a liquid, we increase its disinfection potential.
With our ORP Meter we can measure the ORP level and make sure it is above a certain level. We need it to be high enough to kill the bacteria and viruses, but low enough that it is still safe to drink or swim in.
ORP is the worldwide standard for automatic dosing and disinfection systems for private swimming pools. In general an ORP level between 650 and 750 should give you an optimal, healthy pool with enough disinfection power.
ORP Meter Calibration and Storage
If you are unsure if your ORP meter requires calibration, you can simply put it into a reference solution to check how far off the setpoint it measures. If it is within an acceptable degree, for example +-10mV you do not need to calibrate. Should the difference be higher or lover than 10mV, a calibration is recommended. We advise you to calibrate a least 1 time per month or every time you require the highest accuracy from your ORP meter. Find your ORP Calibration Solution right here.
Always put the protective endcap back on the meter, never let the electrode be exposed to air for a long period of time. We recommend you add a few drops of KCl Storage Solution to the cap of the meter, this will protect the ORP electrode from drying and prolong its lifespan.
