A TDS, EC Water Quality Tester

This compact and portable take anywhere unit with its own protective case is used to test the value of water electrical conductivity of water to determine the purity of the water.

Having both test water temperature and environment temperature functions this nifty device can be widely used for household, personal, at home or while travelling. It can also be used in a domestic garden to full aquaculture, horticulture or farming as a simple field test for preliminary investigations, point sampling of selected areas and ongoing monitoring activities.

What is TDS? Total Dissolved Solids are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm).

Why Should You Measure The TDS Level In Your Water? The EPA Secondary Regulations advise a maximum contamination level (MCL) of 500mg/liter (500 parts per million (ppm)) for TDS. Numerous water supplies exceed this level. When TDS levels exceed 1000mg/L it is generally considered unfit for human consumption. A high level of TDS is an indicator of potential concerns, and warrants further investigation.

Most often, high levels of TDS are caused by the presence of potassium, chlorides and sodium. These ions have little or no short-term effects, but toxic ions (lead arsenic, cadmium, nitrate and others) may also be dissolved in the water. Even the best water purification systems on the market require monitoring for TDS to ensure the filters and/or membranes are effectively removing unwanted particles and bacteria from your water.
