The Xiaomi XMTDS01YM Digital TDS Pen is a compact and efficient water quality tester, perfect for anyone concerned about the purity of their water. This pen-style tester measures Total Dissolved Solids (TDS) from 0 to 9990 ppm, providing an accurate assessment of your water's quality. Whether you're checking the TDS levels of drinking water, pools, or aquariums, this TDS pen gives you quick and reliable readings.

Thanks to its Automatic Temperature Compensation (ATC) feature, the Xiaomi XMTDS01YM delivers precise results even when the water temperature fluctuates. The easy-to-read LCD display shows measurements in PPM or mg/L, and the device is powered by two AAA batteries, making it ideal for everyday use. The device is factory calibrated but can be recalibrated with a TDS solution for ongoing accuracy.

Although water-resistant, this TDS pen is not fully submersible, so always avoid complete submersion. Its lightweight ABS plastic construction ensures durability, while the small size (16 x 2.5 x 1.5 cm) makes it easy to carry around.

Choose Xiaomi XMTDS01YM for its blend of precision, portability, and ease of use. Whether you're a homeowner or a pool enthusiast, this tool will help you keep your water clean and safe.
