Pocket Size TDS Tester Meter for Freshwater Aquariums

A TDS (Total Dissolved Solids) meter, also known as a ppm pen, nutrient tester, or salt tester, is an affordable and convenient digital tool that allows you to instantly check the overall water quality of your fish's environment. This device measures the total amount of dissolved salts, metals, and minerals present in the water, providing a clear indication of its purity.

The TDS-4TMA model utilizes the NaCl (sodium chloride) conversion factor, making it suitable for testing salt levels as well. With a simple push of a button, the TDS-4TMA displays the water's purity level on the screen, measured in parts per million (ppm). The lower the TDS reading, the purer the water, with 0 ppm indicating pure H2O.

This versatile meter is ideal for monitoring the water conditions in your freshwater aquarium, koi pond, or various water filtration and purification systems, such as reverse osmosis (RO) or deionization (DI) units. It is important to note that the TDS-4TMA does not test for biological contaminants.

Featuring a compact and lightweight design, the TDS-4TMA is the smallest and lightest TDS meter available on the market. Its "Hold" function allows you to freeze the measurement, enabling you to view it even when the meter is out of the water. Additionally, the meter's auto-off feature conserves battery life by turning the device off after 10 minutes of inactivity.

To ensure accurate readings, the TDS-4TMA is equipped with Automatic Temperature Compensation (ATC), which automatically adjusts the measurements to account for changes in water temperature. This feature helps to provide reliable and consistent results, regardless of the environmental conditions.

Whether you're a seasoned fishkeeper, a hobbyist maintaining a koi pond, or someone responsible for the operation of a water filtration system, the TDS-4TMA is an invaluable tool that can help you monitor and maintain the optimal water quality for your aquatic ecosystem or purification needs. With its user-friendly design and advanced features, this TDS meter is a must-have for anyone who wants to ensure the health and well-being of their aquatic life or the purity of their water supply.
