Product Description – Portable and lightweight, easy to carry around. – LCD display screen, easy to read the value. – It can be used in water purifiers and filters, drink quality monitoring, pools and spas, aquariums, hydroponics.

Product Description The Pen Type TDS and EC Tester is a portable device used to measure Total Dissolved Solids (TDS) and Electrical Conductivity (EC) in water. TDS indicates the level of dissolved substances like salts and minerals, while EC measures the water’s ability to conduct electricity, which is often related to water quality. This easy-to-use pen helps you quickly check water quality in aquariums, pools, or drinking water to ensure it’s safe and clean.

FRUIT HARDNESS TESTER APPLICATIONS---GY-3 fruit hardness tester can measure the hardness of both hard and soft fruits, while GY-1 or GY-2 can only tester one of them.
