Commercial TDS Water Testing


For applications where pure water is imperative such as food production, beverage production, medical facilities, and more, having a pulse on the TDS levels within the water supply is crucial to your business. Testing your water with a TDS meter or a combination water tester is the most effective way to determine your supply water quality and the product water quality to check the performance of your reverse osmosis water treatment system. We offer handheld testers and in-line TDS monitors which can be installed on your water filtration system to measure and display the levels of total dissolved solids in either the purified water or the feed water used in the RO filtration process. If water testing is a regular practice for your industrial application, Myron digital meters offer optimal accuracy, multiple parameters, and are fast—saving both time and money with this investment.

pH Water Meters


Testing the pH levels of your water supply, for water that has already undergone filtration, is important to determine if the water is at a drinkable level. pH water meters are used in such applications as hydroponics, purification applications, wastewater regulation, aquaculture, colloidal silver, labs and scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment, food & beverage production, and agriculture

Combination Water Testing Equipment


Tests for total dissolved solids (TDS), temperature, and the conductivity of water. These tests are beneficial to determine TDS levels are acceptable and if the water is at your desired or needed temperature. Applications for combination testing equipment include hydroponics, gardening, pools & spas, aquariums & reef tanks, water ionizers, drinking water and more.

Commitment to Water Quality

The access to clean, reliable water is a necessity whether it is in your home or for commercial applications. It is imperative to commercial industries such as medical facilities, pharmaceutical companies, food and beverage production, and more to ensure they are using waters that test at a safe level for pH and TDS for use in their various processes. At wateranywhere, we provide not only traditional water quality testing equipment but also cutting edge technology solutions to guarantee impurities in your water are at a safe, usable level. Our decades of expertise make us your trusted partner in hydration technology.
