Why Your Pool/Spa Water Test Results May Vary | AquaDoc Digital Testing Kit

Ever notice your pool or spa test results aren’t always the same?

In this video, we break down why results may vary when using the AquaDoc Digital Water Testing Kit, what factors affect your readings, and how to get the most accurate results every time.

Acceptable Test Result Ranges

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

 

Small variations in readings are completely normal.

Digital testers measure how light passes through your water sample and compare it against preset calibration values. Factors such as lighting conditions, the age of your test strips, or slight differences in each sample can all influence results, which is expected with any digital testing device.
