Designed to test the water quality in 3 different parameters. It measures EC, CF and TDS without the need to purchase many different meters Electrical conductivity (EC) and Conductivity Factor (CF) measures the ability of a material to conduct electric current while TDS is an expression of mobile charged ions (such as minerals, salts, metals, cations and anions) dissolved in a particular amount of water. The lower the EC, CF and TDS level in water, the higher its purity.

A very useful meter to measure the EC/CF/TDS level in various industries and applications such as aquarium, swimming pool, spa, nutrient, water hardness, food processing, hydroponics, laboratories and other environmental monitoring.
