The formula to estimate the Chlorine Level (ppm) from ORP (mV) is:
\[ \text{Chlorine (ppm)} = \frac{\text{ORP} - 650}{200} \]
Where:
ORP to chlorine conversion is the process of estimating the chlorine level in water based on its oxidation-reduction potential (ORP).
Example 1:
Using the formula:
\[ \text{Chlorine (ppm)} = \frac{750 - 650}{200} = 0.50 \text{ ppm} \]
Example 2:
Using the formula:
\[ \text{Chlorine (ppm)} = \frac{900 - 650}{200} = 1.25 \text{ ppm} \]
