Hanna Marine pH Checker HC HI-780

Product details

Hanna Marine pH Checker HC HI-780 is a compact, handheld pH test/checker for measuring marine-water pH using a colorimetric phenol red method. It’s designed for practical, at-home aquarium water-quality checks where you want an accurate pH reading to support stable conditions for marine aquariums. The checker uses an LED light source and a built-in light detector to read the color change, producing a numeric pH result within the instrument’s stated range.

Features:

• Colorimetric pH testing using the phenol red method
• LED light source with a 525 nm wavelength and a silicon photocell light detector
• Displays results with 0.1 pH resolution for typical hobby monitoring
• Measures within the stated range of 6.3 to 8.6 pH
• Auto-off after ten minutes of non-use to help conserve the battery
• Includes the necessary components to begin testing, including sample cuvette and cap, and a marine pH reagent starter kit
• Supplied with an instruction manual for correct cuvette/reagent use
