Water Testing

We offer equipment for testing water to determine parameters like conductivity, dissolved oxygen, ions, BOD, pH, chlorine, water hardness, water activity, salinity, TDS, TSS, turbidity, and ORP. All our products are carefully made to provide sensitive, accurate test results and to ensure that the results can be repeated. Products employ cutting-edge technology to achieve your goal of receiving results about water that can distinguish between pure and filthy water.
