The HI774 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate from 0.00 to 0.90 ppm. Phosphorus is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results in a few easy steps.
Features at-a-glance:
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for: Aquariums, Environmental, Aquaculture, Water Quality
