A lower ppm reading typically indicates purer water, while higher readings indicate more dissolved content. This TDS pen covers 0–9990 ppm, making it suitable for a wide variety of water sources.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this TDS pen suitable for aquarium and hydroponics use?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This TDS meter is an excellent tool for aquarium keepers who need to monitor water mineral levels for fish health, and for hydroponic growers who want to ensure their nutrient solution is at the correct concentration. The wide 0–9990 ppm range and ±2% accuracy make it a versatile choice for both applications.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I use and maintain the TDS meter?\u003c\/h4\u003e\n\u003cp\u003eA: Using the TDS meter is simple — remove the protective cap, turn it on, and dip the sensor tip approximately 2–3 cm into your water sample. The reading appears on the LCD within seconds. After use, rinse the sensor tip with clean water and replace the cap. The auto-off feature helps preserve battery life between uses.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does a TDS meter actually measure?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A TDS (Total Dissolved Solids) meter measures the concentration of dissolved substances in water — including minerals, salts, and metals — expressed in parts per million (ppm).
