7 in 1 PH Meter with 0.01 Resolution for Aquarium, Pool, Hydroponics, TDS EC ORP

Meet the Yieryi 7-in-1 pH Meter, a versatile digital tester that brings seven essential water-quality measurements into one compact device. It seamlessly supports aquariums, hydroponics, fish tanks, swimming pools, and even cosmetics testing, helping you maintain safe, healthy water with confidence.

With 0.01 resolution, a backlit digital display, and automatic temperature compensation, you get fast, stable readings you can trust. This meter measures pH, EC, TDS, salinity, specific gravity (SG), ORP, and temperature, so you can track all critical parameters at a glance.

Designed for convenience, it features three-point calibration (4.00, 6.86, 9.18) for accurate results, and an anti-interference ORP sensor with a durable electrode design. The instrument offers auto shutdown to save battery life and supports ATC from 32.1°F to 140.0°F (0–60°C).

For saltwater environments, the built-in salt tester covers a range from 0.01% to 25.00% (0–10000 ppm or 10.1–200.0 ppt), helping you keep saltwater pools and hot tubs with salt chlorinators running at peak efficiency.

Benefits & Tips

• Maintain water quality across aquariums, hydroponics, and pools with a single, multi-parameter meter.
• Calibrate easily with three-point calibration to ensure accurate readings over time.
• Use the salt tester to optimize salinity in saltwater pools and hot tubs for efficient chlorination and comfort.
