The HI775 Marine Alkalinity Checker HC is a handheld device designed to measure alkalinity in both marine and freshwater environments accurately. It uses advanced technology such as a fixed wavelength LED light source and a silicon photo detector, providing precise measurements that are typically associated with professional grade instrumentation at the cost of an average chemical test kit. The checker measures alkalinity within a range of 0 to 500 ppm with a resolution of 1 ppm, making it ideal for both casual hobbyists and professionals who require accurate water parameter readings.
