The reaction between phosphorus and the reagent causes a blue tint in the sample. Adaptation of the Standard Methods for the Examination of Water and Wastewater, 18thEdition, Heteropolymolybdenum Blue Method. The reaction between reactive phosphorus and the reagent causes a blue tint in the sample. Environment 0 to 50 °C (32 to 122 °F); max. 95% RH non-condensing Battery Type 1.5V AAA Alkaline Auto-off After 10 minutes of non-use and 2 minutes after reading Dimensions 86.0 x 61.0 x 37.5 mm (3.4 x 2.4 x 1.5”) Weight 64 g (2.3 oz) ORDERING INFORMATION HI736 Checker®HC is supplied with sample cuvette and cap (2 pcs.), Marine Phosphorus Ultra Low Range reagent starter kit (reagents for 6 tests), 1.5V AAA Alkaline battery (1 pc.) and instruction manual. HI706 Checker®HC is supplied with sample cuvette and cap (2 pcs.), Phosphorus High Range reagent starter kit (reagents for 20 tests), 1.5V AAA Alkaline battery (1 pc.), and instruction manual. Reagent Set HI736-25 Reagents for 25 Phosphorus Ultra Low Range tests HI706-25 Reagents for 40 Phosphorus High Range tests Calibration Set HI736-11 Phosphorus Ultra Low Range certified standard kit HI706-11 Phosphorus High Range certified standard kit HI736 Ð HI706 Phosphorus Handheld Colorimeters • Easier to use and more accurate than chemical test kits • Dedicated to a single parameter • Small size, big convenience • Ideal for aquaculture Plants, algae and phytoplankton require phosphorus for nourishment and utilize phosphorous as a component of cell tissue. When organic matter such as plant tissue, dead ¡sh, algae, or uneaten food breaks down aerobically (with oxygen), phosphate is produced, This results in rapid oxygen depletion of aquarium water, which in turn suocates aquatic life and compounds the problem. Phosphorus concentration in water is monitored because it causes corrosion when present in levels too high. Both the Hanna HI736 and HI706 Checker®HC's bridge the gap between simple chemical test kits and professional instrumentation. The Hanna HI736 (for marine applications) and HI706 (for fresh water applications) are both accurate and aordable. The HI736 Checker HC portable handheld colorimeter features a resolution of 1 ppb and ±5 ppb ±5% of reading accuracy and uses an adaptation of the Ascorbic Acid.
