Types of water quality meter in this category

Pocket meters such as the Horiba LAQUAtwin pH-33 and 4EC-33 give quick checks, and handheld meters like the Horiba LAQUA PH220 and DO220 and Hanna HI98190, HI98192 and HI98193 measure pH, ORP, conductivity and dissolved oxygen. Multiparameter meters including the Hanna HI9829 and HI98199, Hach HQ4200, Horiba WQ-330 and YSI ProDSS measure several parameters at once. Turbidity meters (Hach 2100Q, Hanna HI98703, Horiba TB220) and photometers and spectrophotometers such as the Hanna HI97711 and Hach DR1900 complete the range.

How to select a water quality meter

Define the parameters (pH, ORP, conductivity, TDS, salinity, dissolved oxygen, turbidity, chlorine or other chemistry), the ranges and accuracy needed, and whether testing is in the field or lab. Check waterproof rating, data logging, electrodes and reagents, and compliance with methods such as EPA or ISO.
