TDS Meter and pH Meter Digital Water Quality Tester for Drinking Water, Aquariums, Hydroponics, and Pools

The TDS Meter and pH Meter are reliable tools designed for both home and professional use to assess water quality. The TDS Meter measures Total Dissolved Solids (TDS) in parts per million (ppm), conductivity, and temperature, making it ideal for applications such as drinking water testing, hydroponics, aquariums, pools, spas, and more. The pH Meter accurately measures the acidity or alkalinity of water with a range of 0.00-14.00 pH. Both devices are compact, easy to use, and crafted from durable ABS plastic, ensuring portability and longevity.

Description:
TDS Meter Functions:
Measures TDS (0-9999ppm) to determine the concentration of dissolved solids like calcium, magnesium, and sodium in water.
Measures conductivity (0-9999µs/cm) for assessing water purity.
Measures temperature in Celsius (0.1-80.0°C) and Fahrenheit (32.0-176.0°F).
Lock function to hold measurements for easy reading and recording.
Large LCD display for clear, fast, and accurate readings.
Switchable between TDS, conductivity, and temperature units (Celsius/Fahrenheit) with a single button press.
Waterproof design with a low-power processor for extended use.
pH Meter Functions:
Measures pH levels (0.00-14.00) to assess water acidity or alkalinity.
Features a high-sensitivity glass bulb electrode for precise measurements.
Automatic Temperature Compensation (ATC) ensures accurate readings in varying temperatures (0-60°C).
2-point automatic calibration for reliable results.
Simple operation for quick and accurate water quality testing.
