Easy to Use: The TDS meter will lock the measurement result when you press the "HOLD" button and will automatically shut off after several minutes of inactivity. The pH meter has a self-calibration function, allowing for quick readings. Accurate and Reliable: The pH resolution is 0.01pH, with an accuracy of ±0.01pH. The TDS meter ranges from 0 to 9999 ppm, and the conductivity range is 0 to 9999 us/cm, with an accuracy of ±2%. TDS range is 0 to 9999 ppm. Automatic Temperature Compensation: The ATC automatically takes temperature changes into account. Simply turn it on and insert it into a liquid and read the display. Widely Used: Ideal for home or laboratory use; suitable for testing the pH balance of drinking water, swimming pools, aquariums, RO systems, spas, or hydroponics. The small size makes it convenient to carry. Warm Tips: Remember to wipe off the water on the surface of the pH meter after use and keep it dry, then replace the pen cap.
