Product Description
Professional High Range Phosphorus Colorimeter for Wastewater & Industrial TestingThe Hanna HI706 Checker HC is a portable, professional-grade high range phosphorus colorimeter designed for accurate phosphate (PO₄³⁻) measurement from 0.00 to 100.0 mg/L in wastewater, industrial effluent, and environmental water quality applications. This handheld photometer delivers lab-quality results in the field with simple operation—just add reagent, insert the cuvette, and read phosphorus concentration on the easy-to-read LCD display.Key Features:
High Range Precision: Measures phosphorus from 0.00 to 100.0 mg/L (ppm) PO₄³⁻ with ±1 mg/L accuracy—ideal for wastewater, industrial effluent, and high-phosphorus applications
Portable & Handheld: Compact Checker HC design fits in your pocket for on-site testing anywhere
Lab-Quality Results: Advanced photometric technology delivers accurate, repeatable measurements comparable to benchtop instruments
Simple Operation: Easy three-step process—fill cuvette, add reagent, read result—no complex procedures
LCD Display: Large, easy-to-read screen shows phosphorus concentration in mg/L (ppm)
Auto-Off Function: Conserves battery life with automatic shutdown after non-use
CAL Check: Built-in validation feature verifies meter performance for quality assurance
Complete Kit: Includes meter, sample cuvettes, reagents for initial testing, and carrying case

Why Test Phosphorus Levels?Phosphorus testing is critical for environmental protection and regulatory compliance. Excessive phosphorus in wastewater discharge causes eutrophication—algae blooms that deplete oxygen and harm aquatic ecosystems. The EPA and state agencies regulate phosphorus discharge limits to protect water quality. The HI706's high range (0-100 mg/L) is specifically designed for wastewater treatment plants, industrial effluent monitoring, and applications where phosphorus levels are elevated and require accurate measurement for compliance reporting.How to Use:
Fill cuvette with 10 mL water sample to line
Add HI706 reagent packet and mix thoroughly
Wait for color development (2 minutes)
Insert cuvette into HI706 Checker HC
Press button to read phosphorus concentration in mg/L
Reagent Availability:Replacement reagents available separately as HI706-25 (25 tests) and HI706-100 (100 tests). Each reagent packet is pre-measured for consistent, accurate results.Maintenance & Care:Clean cuvettes with distilled water after each use. Store in protective case when not in use. Replace battery when low battery indicator appears. Use CAL Check feature periodically to verify meter performance. Keep reagents stored in a cool, dry place.Note: Reagents sold separately after initial supply is used. For best results, use fresh reagents and follow all testing procedures carefully. Regular CAL Check validation recommended for quality assurance.
