Frequently Asked Questions
Q: What does a TDS water tester pen measure?
A: A TDS (Total Dissolved Solids) water tester pen measures the concentration of dissolved substances — such as minerals, salts, and metals — in water. The reading is displayed in parts per million (ppm), giving you a quick snapshot of your water's overall composition. This tester covers a range of 0–999 ppm, making it suitable for drinking water, pools, aquariums, hydroponics, and more.
Q: Is the TDS water tester pen easy to use?
A: Absolutely. Simply remove the protective cap, power on the device, and dip the alloy probe into your water sample. The LCD screen displays a stable reading within seconds — no complicated setup or calibration needed. It's designed for everyday use at home, in the garden, or on the go.
Q: What water sources can I test with this TDS pen?
A: This portable TDS tester is versatile enough for a wide range of applications including tap water, filtered or purified drinking water, swimming pools, fish tanks and aquariums, hydroponic nutrient solutions, irrigation or agricultural water supplies, and aquaculture systems. Its 0–999 ppm range covers most common water quality scenarios.
Q: How do I care for and maintain the TDS tester pen?
A: After each use, rinse the alloy probe with clean water and gently pat it dry before replacing the protective cap. Avoid bending or dropping the probe tip. Store in a cool, dry place when not in use to help maintain accurate readings over time.
