General description The 5-in-1 Digital Seawater Salinity Tester is a versatile tool designed for monitoring water quality. It measures TDS, pH, salinity, electrical conductivity (EC), and temperature, making it ideal for both seawater and food salinity testing. The device features a high-precision algorithm chip and electrodes for accurate and fast responses. With a backlit LCD screen, users can easily view measurements in various conditions, and the auto-off function helps conserve battery life.
