Labtron TDS Tester provide measurement of dissolved solid concentration in water up to 1000 ppm. Their electrode probe measures electrical properties of liquid to determine the level of soluble substance. They feature sensors that detect conductivity change, converting them into readings to display on screen. Their battery life is long lasting that minimizes need for frequent replacement or recharges. Our TDS Tester is applicable for hydroponics, water purification, beverage production and testing drinking water quality.




Labtron Pocket TDS tester is versatile and can measure TDS levels in a variety of water sources including drinking water, wastewater, swimming pools, and aquarium water. It is also suitable for educational and industrial applications where monitoring water purity is essential. Its low TDS measurement range makes it ideal for testing water that requires precise TDS control. This makes it a valuable tool for ensuring water quality across different environments.
The Pocket TDS tester features a simple 1-point push button calibration system that allows for quick and hassle-free adjustments. For calibration, users should use a 71.8 ppm calibration solution, which helps align the meter for accurate readings. This feature ensures consistent accuracy without needing complex multi-point calibrations. Even first-time users can perform the calibration with minimal guidance.
Yes, our Pocket TDS tester is designed with a waterproof casing, making it suitable for use in humid or harsh working environments. The tester remains protected from accidental water exposure, whether you are working near pools, wastewater tanks, or laboratories. This rugged design extends the life of the device and enhances reliability. It is a dependable choice for both indoor and outdoor use.
Labtron's Pocket TDS tester features automatic temperature compensation between 0 °C and 50 °C since temperature plays a crucial role in TDS measurement. This ensures accurate readings regardless of water temperature within the operational range. The built-in temperature coefficient of 2% per °C adjusts the readings accordingly. This feature makes it ideal for environments where water temperature may fluctuate.
The Pocket TDS tester's platinum sensor provides rapid response times and reliable accuracy for TDS readings. It is less prone to corrosion compared to other materials, offering better durability and consistent performance over time. This contributes to more stable results and less frequent recalibration. Users benefit from both precision and long-term cost efficiency.
Our Pocket TDS tester runs on three 1.5 V “G13A” batteries and offers a battery life of approximately 150 hours. It features an automatic power-off function that activates after 8 minutes of inactivity to conserve energy. This helps prevent unnecessary power drainage when the device is not in use. Manual power-off is also available for user convenience.
