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.\u003c\/p\u003e\n\u003cp\u003eTest Range: 0–200 ppb (µg\/L) | Method: Colorimetric | Compatible Reagents: HI 774-26 | Battery: 1.5V AAA\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":49370990411915,"sku":"TE-HI-0011","price":125.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0579\/8353\/3195\/files\/hanna-instruments-checker-handheld-colorimeterapex-aquatic-6930532.jpg?v=1789216696","url":"https:\/\/apexaquatic.com.au\/products\/hanna-instruments-checker-handheld-colorimeter-phosphate-ultra-low-range","provider":"Apex Aquatic","version":"1.0","type":"link"}
