✔ 4-in-1 multi-parameter testing: Combines measurement of TDS, electrical conductivity (EC), and temperature (°F) in a single compact device, eliminating the need for multiple instruments and simplifying water quality monitoring.
✔ User-friendly and energy efficient design: Features an easy dip-and-read operation with auto-lock holding the measured value, a large backlit display for readability in low light, and an automatic shut-off after two minutes to save battery life.
