Why PoolWaterLAB Is the Most Accurate Digital Pool Water Tester
PoolWaterLAB is a professional digital photometer designed for precise pool and spa water testing. Unlike test strips or visual color-matching kits, it delivers lab-grade accuracy that ensures stable, safe, and balanced water in every condition.
Accurate chemical balance isn’t just about pH or alkalinity — it’s about understanding the interaction between cyanuric acid (CYA) and free chlorine (FC). Without a photometer, it’s impossible to correctly measure and compensate for this relationship, which defines the true sanitizing strength of your water and determines how effectively chlorine protects against bacteria and algae.
Built for both residential owners and professional service technicians, PoolWaterLAB measures every critical parameter quickly and consistently — helping you maintain perfect, data-driven water quality with total confidence.
Photometric Water Analysis
-
Photometric Measurement Principle
PoolWaterLAB uses reagent-based photometric analysis to measure chemical concentrations in pool and spa water by analyzing controlled light transmission through a reacted water sample.
-
Consistent and Repeatable Results
Designed to deliver consistent measurement results when standardized testing procedures are followed, supporting reliable water chemistry control over time.
-
Designed by Pool Industry Experts
Developed by professionals with hands-on experience in pool and spa service, maintenance, and water chemistry.
Photometric Testing Demonstration
This video demonstrates the photometric testing procedure used by PoolWaterLAB during routine pool and spa water analysis.
A water sample is combined with a specific reagent, initiating a controlled chemical reaction. The photometer then measures light transmission through the reacted sample and calculates the concentration of the target parameter, displaying the result as a clear digital value (ppm).
This method ensures consistent, objective results and eliminates the subjectivity of visual color-matching tests — making PoolWaterLAB a professional-grade solution for accurate pool and spa water chemistry control.
Intended Users
-
Pool and Spa Owners
For residential pool and spa owners who want professional-grade water analysis using the same testing principles applied by service companies.
Field-tested reliability provides greater confidence compared to basic consumer testing methods. -
Pool Service Professionals
PoolWaterLAB was developed specifically for field use by professional pool service technicians.
The instrument is designed to provide reliable, repeatable measurements during daily service operation.
What Accurate Testing Changes
-
Stop Guessing
Get consistent digital readings instead of subjective color matching. Less confusion, more control.
-
Fix Problems Faster
Identify the real cause of cloudy water and recurring algae—especially when CYA affects chlorine effectiveness.
-
Use Fewer Chemicals
Adjust only what you actually need based on accurate numbers, not estimates or “shock and hope.”
Technical Overview
PoolWaterLAB is designed as a professional photometric instrument for swimming pool and spa water analysis, combining precise chemical measurement with modern data connectivity.
The device operates using reagent-based photometric measurement. After a specific reagent is added to the water sample, PoolWaterLAB analyzes controlled light transmission through the reacted sample to determine the concentration of the target parameter with laboratory-level accuracy.
Measurement results are displayed as clear digital values (ppm) and can be securely transmitted via Bluetooth or Wi-Fi to the PoolWaterLAB Cloud platform and companion mobile application.
The connected application supports test history tracking, cloud data storage, and automatic chemical dosing calculations based on measured values — helping standardize water treatment decisions across service operations.
For professional service companies and developers, PoolWaterLAB also provides an open API that enables system integration, custom software development, and workflow automation.
