Hanna Phosphate High-Range Checker® HC - HI717

The Hanna HI717 Phosphate High-Range Checker HC is a professional-quality digital colorimeter engineered to deliver high accuracy in phosphate measurement for water testing in laboratory, industrial, or field environments. With a measurement range of 0.0 to 30.0 ppm, an accuracy of ±1.0 ppm ±5% of reading, and a 0.1 ppm resolution, it provides dependable results far superior to standard test kits.

The HI717 uses an LED at a fixed wavelength of 525 nm and a silicon photocell to ensure precise and repeatable readings, based on the Heteropolymolybdenum Blue method. A built-in timer and one-button operation streamline testing workflows, making the instrument suitable for water treatment facilities, industrial quality control, aquaculture, and environmental monitoring applications.

• Designed for long-lasting operation with automatic shut-off after ten minutes of non-use, maximizing battery efficiency.
• Works reliably in challenging laboratory and onsite conditions (0 to 50°C, RH up to 95%).
• Compact form factor (81.5 × 61 × 37.5 mm) and only 64 g make it highly portable for fieldwork.
• Supplied with easy-to-replace (1) 1.5V AAA battery.
• Utilizes the well-regarded Standard Methods for the Examination of Water and Wastewater, 18th edition.

Widely adopted in laboratory, water treatment, industrial, agricultural, and aquaculture environments for high-accuracy phosphate testing.
