Water Test Kits & Analysis Meters

Good treatment starts with knowing what's in the water. We carry test kits and meters for hardness, chlorine, pH, TDS, arsenic and more — from Hanna, HM Digital, Watts and Sensafe — from quick test strips to lab-grade reagent kits and checkers.

How to choose a test kit

Strips vs. reagent vs. meter. Strips are fast and cheap; titration/reagent kits are more precise; digital meters are best for ongoing monitoring.
Test what matters. Hardness and chlorine for softener/filter sizing; TDS for RO performance; arsenic/nitrate for well safety.
Keep reagents fresh. Reagents and buffers have shelf lives — replace them to keep results trustworthy.
Calibrate meters. pH and conductivity meters need periodic calibration with the matching standard.

Tell us what you need to test and we'll match the kit. Ask us.
