Q & A
Why Should I Test My Drinking Water?
Testing your drinking water helps you identify potential contaminants, imbalances, or issues that are not visible to the naked eye, ensuring it's safe and healthy for consumption.
What Parameters Do Your Water Quality Testers Typically Measure?
Our testers can measure multiple parameters including pH, TDS (Total Dissolved Solids), EC (Electrical Conductivity), ORP (Oxidation-Reduction Potential), Salinity, Hydrogen (Hâ‚‚), and Temperature.
How Often Should I Calibrate My Water Quality Tester?
It's recommended to calibrate your pH meter before each use or at least once a week, especially when testing different water sources, to ensure consistent accuracy.
What Is ATC (Automatic Temperature Compensation) ?
ATC automatically adjusts the measurement reading to compensate for temperature variations, ensuring higher accuracy even if the water temperature changes during testing.
What Is TDS And What Does A High TDS Reading Indicate?
TDS (Total Dissolved Solids) measures the total concentration of dissolved substances in water. High TDS can indicate hard water, presence of minerals, salts, or even some contaminants, potentially affecting taste.
Can I Use These Testers For Purposes Other Than Drinking Water, Like Aquariums Or Pools?
While some parameters might be applicable, our drinking water testers are specifically designed and calibrated for drinking water. For aquariums or pools, we recommend using specialized testers designed for those environments.
