Water Quality Analyzer

What it does

A water quality calculator that rates pH, EC and temperature readings against fixed ranges and exports a PDF report.

When to use it

Use it to check whether a water or nutrient-solution reading is in range before use.

How it calculates

• pH Good: 6.0–7.0; Fair: 5.5–6.0 or 7.0–7.5; Poor: below 5.5 or above 7.5
• EC Low (Good): below 0.7; Medium: 0.7–1.0; High: above 1.0
• Temperature Good: 18–22 °C; Fair: 15–18 or 22–26 °C; otherwise Poor
• Overall "Optimal" requires Good pH, Low EC and temperature that is not Poor
