Hanna Instruments Marine Algae & Nutrient Management Kit Easy-to-read, instant digital results Compact and portable Simple one-button designs and straightforward steps Ideal for testing saltwater aquariums, reef tanks, and other marine and aquaculture applications. Easily control nutrients, prevent algae, and maintain reef balance. This kit arrives with everything you need to keep both saltwater parameters in check to ensure a healthy and thriving environment. Stop guessing with color charts. Get fast, accurate digital readouts in the palm of your hand with these CheckersHC. Includes: Marine Phosphate Ultra Low Range(ppm) Marine Nitrate High Range Extra set of reagents for each checker More info: Marine Phosphate Ultra Low Range CheckerHC The HI774 Marine Phosphate Ultra Low Range CheckerHC is a precise and cost-effective way to measure phosphate in saltwater aquariums and marine applications. Testing for orthophosphates is standard practice and provides valuable insight into your reef tank's water chemistry to help ensure long-term coral health. Phosphate is an important parameter to measure because levels that are too high can lead to extensive algae growth and prevent coral calcification and development. Specifications Range 0.00 to 0.90 ppm Resolution 0.01 ppm Accuracy@ 250C/770F ±0.02 ppm of reading Light source Light Emitting Diode@525 nm Light detector Silicon photocell Method Adaptation of Standard Methods for the Examination of Water & Wastewater, 20th Edition, Ascorbic Acid Method. The reaction between phosphate and the reagent causes a blue tint in the sample. Auto shut-off After 7 min of non-use and 2 min after reading Environment O to 50 oc (32 to 122 OF): max. RH non-condensing Battery type 1.5V AAA Alkaline What's Included: H1774 CheckerSHC is supplied with sample cuvettes and caps (2 pcs.), Marine Phosphate ULR Reagent starter kit for 10 tests, battery, and instructions. Marine Nitrate High Range CheckerHC The HI782 Marine Nitrate High Range CheckerHC is specifically designed to quickly and accurately determine high levels of nitrate for saltwater aquariums and marine applications. With a digital readout, there is no need to determine colors visually. Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in aquariums can facilitate the growth of undesirable organisms such as algae and dinofiagellates. Specifications Range 0.0 to 75.0 ppm (as NO.-) Resolution 0.1 ppm Accuracy@ 250C/770F ±2.0 ppm ±5% of reading Light source Light Emitting Diode@525 nm Light detector Silicon photocell Method Zinc reduction method. The reaction between nitrate and the reagent causes a pink tint in the sample. Auto shut-off After 10 minutes of non-use Environment O to 50 OC(32to 122 OF); max. 95% RH non-condensing Battery type 1.5V AAAAlkaline What's Included: H1782 CheckerHC is supplied with sample cuvettes and caps (2 pcs.), Marine Nitrate HR Reagent starter kit for 10 tests, a 3 mL pipette, battery, and instructions.
