Phosphorus is one of the essential minerals for health. One of the best natural ways to obtain it is through the consumption of certain foods that provide this benefit.
The lack of phosphorus in our body can lead to a variety of disorders, and maintaining adequate levels can help prevent many health issues.

Plants, algae, fish food, and even tap water contain phosphorus. The combination of all these factors may cause the phosphorus levels in your aquarium to become excessive, leading to potential issues. Phosphate is a contributing factor to excessive algae growth, so it is crucial to keep levels as close to zero as possible.

The HI736 Phosphorus Meter is positioned between basic test kits and professional photometers. This phosphorus checker is accurate and cost-effective. It offers a resolution of 1 ppb (200 points) and an accuracy of ± 5 ppb ± 5% of the reading.

It features a very comfortable design. It fits in the palm of your hand and can easily be carried in your pocket. Additionally, its LCD screen is large and easy to read, and the automatic shut-off function ensures the battery life is preserved in case you forget to turn it off.

HANNA Checkers are small, portable, and, above all, provide more accurate results than typical chemical test kits. Offering enhanced technology, their simple design allows for easy and hassle-free measurements.

These digital photometers or test kits serve as a bridge between basic test kits and professional instruments, such as a calibratable photometer. Conventional test kits are not accurate and depend entirely on the user’s interpretation of color, which is why HANNA has digitized this process and created an exact pocket-sized colorimeter.

The Checker® is precise and offers a very affordable price.

The innovative shape of the Checker ensures it fits comfortably in your hand or pocket. Additionally, the LCD screen is easy to read, and the automatic shut-off function helps ensure the battery is not drained if you forget to turn it off.
