Hanna Instruments Checker Handheld Colorimeter for Nitrate High Range is a professional-grade digital colorimeter designed to deliver fast, accurate, and reliable nitrate measurements across a broad concentration range in freshwater aquariums, ponds, and aquaculture systems. This high range checker is ideal for detecting and monitoring elevated nitrate levels in systems where nutrient accumulation may be significant, such as heavily stocked freshwater tanks, koi ponds, and aquaculture facilities. Unlike traditional drop-based test kits that rely on subjective colour interpretation, the Hanna Checker eliminates human error by electronically reading and displaying precise nitrate values in ppm (mg/L), providing laboratory-quality accuracy in a compact handheld device. Replacement reagent kits are available separately.
Test Range: 0–150 ppm (mg/L) NO3 | Method: Colorimetric | Compatible Reagents: HI 782-26 | Battery: 1.5V AAA
