The HI702-25 are high-quality pre-measured reagents designed for use with the Copper High Range Checker HC. These reagents utilize the Bicinchoninate Method where a reaction between copper and the reagent produces a purple tint in the sample. By simply adding the packet to the water sample, the checker determines the concentration based on the resulting color, displaying results directly in ppm of copper.

Each package contains 25 individual test packets that follow an adaptation of the EPA method for accuracy and reliability. The testing range is specifically calibrated to measure expected concentrations between 0.00 and 5.00 ppm of copper. This ensures precise monitoring for aquarium environments where maintaining specific metal levels is critical for the health of inhabitants.

These reagents are ideal for reef hobbyists who need to monitor high-range copper levels without complex equipment or lengthy procedures. Whether managing a quarantine tank or treating specific ailments, accurate measurement helps prevent overdosing and ensures system stability. Consistent testing with these reliable packets supports long-term aquarium success and coral health.
