Precise copper monitoring is critical when using copper-based medications for treating fish diseases such as ich and velvet, as effective treatment requires maintaining copper within a narrow therapeutic range. Unlike traditional drop-based test kits that rely on subjective colour interpretation, the Hanna Checker eliminates human error by electronically reading and displaying precise copper values in ppm (mg\/L), providing the accuracy required for safe and effective copper treatment. Replacement reagent kits are available separately.\u003c\/p\u003e\n\u003cp\u003eTest Range: 0.00–6.00 ppm (mg\/L) | Method: Colorimetric | Compatible Reagents: HI 702-26 | Battery: 1.5V AAA\u003c\/p\u003e","brand":"Hanna Instruments","offers":[{"title":"Default Title","offer_id":49370991001739,"sku":"HI-8975","price":114.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0579\/8353\/3195\/files\/hanna-instruments-checker-handheld-colorimeterapex-aquatic-3694011.jpg?v=1789216750","url":"https:\/\/apexaquatic.com.au\/products\/hanna-instruments-checker-handheld-colorimeter-copper-low-range","provider":"Apex Aquatic","version":"1.0","type":"link"}
