เครื่องวัดคุณภาพน้ำ วัดสิ่งเจือปนในน้ำ 3-in-1 meter (EC-1385) Waterproof EC CF TDS Meter Tester 19990 ppm Aquarium
This 3-in-1 meter (EC-1385) is a device to measure water quality in 3 different parameters in EC, CF and TDS. Electrical conductivity (EC) and Conductivity Factor (CF) measures ability of a material to conduct electric current. TDS is an expression of mobile charged ions (such as minerals, salts, metals, cations and anions) dissolved in particular amount of water. The lower the EC, CF and TDS level, the high the purity of water is.
This meter is featured with Waterproof design with Replaceable TDS electrode. EC-1385 is a very useful meter to measure the TDS level in various industries and applications such as Hydroponics, Aquariums, Water Hardness, Swimming Pools, Spas and Laboratories.
