Hanna Instruments Checker Handheld Colorimeter for Phosphate Ultra Low Range is a professional-grade digital colorimeter designed to deliver precise and reliable phosphate measurements at extremely low concentrations in reef and marine aquariums. Capable of detecting phosphate levels as low as 0 ppb, this ultra-sensitive checker is the ideal testing solution for reef hobbyists maintaining the very low phosphate levels required for a healthy and thriving SPS coral dominated reef aquarium. Unlike traditional drop-based test kits that rely on subjective colour interpretation, the Hanna Checker eliminates human error by electronically reading and displaying precise phosphate values in ppb (µg/L), providing laboratory-quality accuracy in a compact handheld device. Replacement reagent kits are available separately.
Test Range: 0–200 ppb (µg/L) | Method: Colorimetric | Compatible Reagents: HI 774-26 | Battery: 1.5V AAA
