Understanding Your Eagle Ray Digital Water Tester Readings

The Eagle Ray Digital Water Testing Kit for pools and spas makes it easy to measure key water parameters accurately and quickly. Like all digital testers, it is normal to see slight variations in readings. This guide will help you understand what ranges and tolerances are considered normal, so you can feel confident about your water balance.

How to Use This Guide

Use the chart below to compare your Eagle Ray readings with the expected ranges. If your results fall within the tolerances listed, there is no need to worry. These variations are standard for digital photometers and are consistent with industry guidelines.

Typical Ranges and Expected Tolerances

 

Parameter Acceptable Variation
Free Chlorine (FCL) ±0.30 ppm
Total Chlorine (TCL) ±0.30 ppm
Bromine (Br) ±1 ppm
Cyanuric Acid (CyA) ±40 ppm
Alkalinity (Alk) ±50 ppm
Total Hardness (TH) ±80 ppm
pH ±0.4


Why Are Small Variations Normal?

Digital testers work by measuring light through your water sample and comparing it to calibrated values. Factors like lighting, test strip age, and even slight differences in water samples can create small variations. These tolerances are normal and expected in any digital testing system.
