4-in-1 water quality tester

Description

Portable instrument for checking water quality. It can measure pH, electrical conductivity (EC), total dissolved solids (TDS), and temperature. It features a rustproof and corrosion-resistant probe and an LCD display. Ideal for checking the quality of drinking, spring, and tap water, and in applications such as hydroponics and gardening, swimming pools and wellness centers, aquariums and tanks, water ionizers, water filters, etc.

The package includes: the instrument, 3 LR44/AG13 1.5-volt button batteries, and two powder solutions for pH testing (one with pH 4.01 and one with pH 9.18).
