Benefits of the HI-733 Checker HC

Superior Accuracy Compared to Test Kits

The HI-733 Checker HC provides a clear digital readout, eliminating the guesswork involved in interpreting color changes on test strips. With its high sensitivity, the device ensures you can monitor and maintain proper ammonia levels in your freshwater system.

Reliable and User-Friendly

This handheld colorimeter uses the established Nessler Method, where ammonia reacts with the reagent, creating a yellow tint. The intensity of this tint is measured to determine the ammonia concentration, making testing quick, accurate, and easy.

Ideal for Multiple Applications

The HI-733 is perfect for monitoring freshwater aquariums, wastewater systems, water quality, education, and more. Use it to ensure the health of aquatic environments or for research and environmental assessments.
