This high range checker is ideal for detecting and monitoring elevated phosphate levels in systems where nutrient levels may be significantly higher than in a typical reef aquarium, such as heavily stocked freshwater tanks, planted aquariums with high fertiliser dosing, or pond environments. 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 ppm (mg\/L), providing laboratory-quality accuracy in a compact handheld device. Replacement reagent kits are available separately.\u003c\/p\u003e\n\u003cp\u003eTest Range: 0.0–30.0 ppm (mg\/L) | Method: Colorimetric | Compatible Reagents: HI 717-26 | Battery: 1.5V AAA\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":49370990575755,"sku":"HI-7470","price":109.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0579\/8353\/3195\/files\/hanna-instruments-checker-handheld-colorimeterapex-aquatic-6576381.jpg?v=1789216750","url":"https:\/\/apexaquatic.com.au\/products\/hanna-instruments-checker-handheld-colorimeter-phosphate-high-range","provider":"Apex Aquatic","version":"1.0","type":"link"}
