- Improved water testing: This TDS meter accurately and quickly checks soluble salt content, ionic organic matter, and other impurities in water, providing a clear indication of water quality. It responds in about 3 seconds, making it suitable for testing at home or outdoors. - Accurate readings with durable probe: Features a durable titanium alloy probe that helps ensure reliable TDS measurements and consistent results. - Lock function for easy viewing: The lock (hold) function lets you freeze the LCD reading for convenient viewing, eliminating guesswork. - Efficient and user-friendly: Automatically shuts off after 5 minutes of inactivity to save battery life, and readings stabilize within seconds after turning on and stirring the water. - Use scenarios: 1) Check drinking water quality from tap or bottled water at home. 2) Verify water quality from home filtration systems (RO or pitcher) to confirm low TDS levels. 3) Assess water for outdoor use, aquariums, or hydroponics to ensure suitable water conditions.
