Hanna HI736 Phosphorus Ultra Low Range Checker HC
The Hanna HI736 Phosphorus ULR Checker HC is a handheld digital colorimeter designed for ultra low range phosphorus testing in water. Tailored for applications requiring high sensitivity—such as marine aquariums, aquaculture systems, research labs, and environmental monitoring—this checker fills the gap between basic chemical test kits and sophisticated instrumentation.
By using the colorimetric method and a precise LED photodetector, the HI736 delivers fast, accurate readings with 1 ppb resolution, making it ideal for users who demand both reliability and ease of use in ultra low phosphorus detection.
Key Features
Ultra Low Detection Range: Ideal for environments where phosphorus levels must be tightly controlled (e.g., reef tanks and sensitive aquatic habitats).
High Accuracy & Resolution: Provides ±5% of reading ±10 ppb accuracy with 1 ppb resolution for precise monitoring.
Compact & Portable: Palm-sized design makes it easy to carry and use in the field or lab.
Simple 4-Step Testing: Streamlined testing process requiring minimal training.
Digital Readout: Eliminates the guesswork of interpreting color strips or visual charts.
Auto Shut-Off: Conserves battery life by turning off after 3 minutes of inactivity.
Typical Applications
Marine and Reef Aquariums
Environmental Water Monitoring
Aquaculture Facilities
Laboratory Research
Nutrient Management Programs
