More info
The HI781 Nitrate Checker HC by Hanna Instruments is a simple and accurate handheld colorimeter that uses the Beer-Lambert principle to determine nitrate concentration. The HI781`s low range of 0.00 - 5.00 makes it ideal for measuring the low nitrate levels found in saltwater aquariums.
Why are Nitrate levels important?
Excess nitrates in a reef system can lead to an overgrowth of undesirable algae and dinoflagellates. Alternatively, not enough nitrates can lead to starvation for SPS and other corals.
Features:
- Designed to accurately determine nitrate levels in aquariums and marine biology applications
- Low range is ideal for saltwater aquariums
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Simple one-button operation
- Large LCD digital read out for added convenience
- Auto shut-off to assure the battery wont be drained
- Compact size for easy travel and storage
