- Automatic Detection: Effortlessly measure the specific gravity of seawater in fish ponds and tanks, thanks to the hydrometer's ability to automatically detect water sample density. - User-Friendly Operation: Designed for ease of use, simply submerge the seawater densimeter to a depth of 15cm (6 inches) to obtain accurate readings, eliminating errors caused by surface oil films. - Hygienic Design: Maintain the integrity of your aquaculture environment by using the densimeter while keeping your hands clean, preventing contamination of the seawater. - Precise Measurements: The ocean hydrometer delivers reliable readings with an accuracy of ±0.002 specific gravity units, ensuring precise monitoring in fish ponds within a temperature range of 20-30°C. - Durable Material: Constructed from transparent plastic, the Sealevel automatic hydrometer is not only easy to read but also robust, making it suitable for marine aquariums and aquaculture applications. Use Cases: 1. Monitor salt levels in your marine aquarium to create an optimal environment for fish health. 2. Regularly check the specific gravity of seawater in a fish pond to ensure ideal conditions for aquatic life. 3. Simplify your aquaculture management routine with quick and accurate readings for effective water quality assessment. Experience the convenience and reliability of the Sealevel automatic hydrometer for your aquatic needs.
