Digital EC CF TDS Conductivity Meter 19990ppm ****           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. In addition, the meter has a replaceable electrode that can be replaced anytime and 100% waterproof design that can withstand the wet environment. A very useful meter to measure the TDS level in various industries and applications such as aquarium, swimming pool, spa, nutrient, water hardness, hydroponics and laboratory. Special Features 3 parameters: EC, CF, TDS with one electrode Fully Waterproof design to withstand wet environment Replaceable electrode Large and clear LCD display Data Hold function saves measured values for later use Quick & highly accurate measurement Built-in Automatic Temperature Compensation (ATC) Factory pre-calibrated (mini-screw driver is included for re-calibration if necessary) Brand new in box ready to be operated upon arrival Specifications Measuring range: EC: 0.00 ~ 19.99 EC CF: 0.0 ~ 199 CF TDS: 10 ~ 19990 ppm Resolution: EC: 0.01 EC CF: 0.1 CF TDS: 10 ppm Accuracy: ±2% Full Scale (F.S.)
