How it works
PoolWaterLAB is a digital pool and spa water tester that uses photometric analysis to measure chemical parameters and convert them into numerical results. This page explains the general measurement principle demonstrated in the video above.
Photometric measurement principle
Photometric testing is based on how light interacts with a prepared water sample. When a reagent reacts with a specific parameter, it produces a color intensity proportional to the concentration of that substance. The photometer measures the amount of light absorbed by the sample and converts this optical signal into a digital value.
From water sample to digital result
After the chemical reaction is complete, the device analyzes the optical signal and applies a predefined method to calculate a numeric result. This approach reduces subjective interpretation compared to visual color matching and provides repeatable readings when measurements are performed under recommended conditions.
Why photometric testing is used
- Reduces user-dependent color interpretation
- Provides numerical results instead of visual estimates
- Supports repeatable measurements with consistent procedures
- Commonly used in laboratory and field water analysis
