HI702 Copper Checker® HC High Range Colorimeter – Accurate Digital Copper Testing
Eliminate the guesswork of color chart matching with the HI702 Checker® HC handheld colorimeter. This pocket-sized digital tester delivers precise high-range copper measurements (0-5 ppm) with lab-quality accuracy, making it the perfect alternative to subjective chemical test kits for aquariums, pools, plating operations, and water quality monitoring.
Why Choose HI702 Copper Checker HC?
-
Digital precision – Eliminates subjective color chart interpretation with direct digital copper readings to 0.01 ppm resolution
-
High range capability – Measures 0.00 to 5.00 ppm copper for industrial, plating, and high-concentration applications
-
One-button simplicity – Simple operation makes getting accurate copper results effortless, even for first-time users
-
EPA-adapted method – Uses bicinchoninate reagent reaction (purple tint) for reliable, industry-standard measurements
-
Fresh or saltwater compatible – Works with both freshwater and marine applications
-
Ultra-portable – Pocket-sized design (3.4" x 2.4" x 1.5") weighs just 2.3 oz for easy field testing
-
Cost-effective accuracy – More accurate than chemical test kits at a fraction of benchtop instrument costs
-
Auto shut-off – Conserves battery with automatic 10-minute power-down
How It Works
The HI702 uses an EPA-adapted colorimetric method where copper reacts with bicinchoninate reagent to produce a purple tint proportional to copper concentration. The built-in LED light source (575 nm) and silicon photocell detector measure the color intensity and display the precise copper concentration digitally – no color chart matching required.

Applications
Essential for high-range copper monitoring in marine and freshwater aquariums (copper-based medications), swimming pools and spas (algaecide residue), electroplating and metal finishing operations, industrial wastewater treatment, drinking water quality testing, environmental compliance monitoring, and educational laboratories. The 0-5 ppm range is ideal for applications where copper concentrations exceed typical low-range testing capabilities.
Why Choose a Checker HC Over Test Kits?
-
Eliminates subjectivity – No more squinting at color charts or debating between shades
-
Better accuracy – Digital precision vs. visual estimation
-
Faster results – Direct digital readout saves time
-
Consistent performance – LED light source ensures repeatable measurements regardless of ambient lighting
-
Professional credibility – Lab-quality results for compliance and documentation
