Accurate water testing is essential for healthy aquatic systems — from hatcheries and recirculating aquaculture to research tanks and pond installations. Our range of water quality meters provides reliable instruments and kits to measure key parameters including dissolved oxygen (D.O.), pH, ORP (oxidation-reduction potential), salinity, total dissolved gas pressure (TGP), turbidity, and more.


These meters and test kits are designed for both field and laboratory use, whether you’re verifying oxygen levels for aeration performance, monitoring pH in sensitive environments, or checking salinity and conductivity in marine systems. Models range from handheld, single-parameter instruments to advanced multiparameter meters with interchangeable probes for comprehensive water quality oversight.


Pair water quality meters with other essential tools such as dissolved oxygen meters, multiparameter instruments, and reagent test kits to create a complete monitoring solution. Regular testing helps you make informed decisions about aeration, filtration, and chemical conditioning — improving aquatic health, operational consistency, and species performance.
