BRAND NEW HANNA HI 3823 COMBINATION TEST KIT FOR AQUACULTURE: Alkalinity, Carbon Dioxide, Dissolved Oxygen, Hardness, pH and Salinity. HI 3823 Combination Test Kit for Aquaculture HI 3823 provides you with the most important test parameters for aquaculture applications: alkalinity, carbon dioxide, dissolved oxygen, hardness, pH and salinity.Each of these parameters plays a critical role in the delicate balance of the aquatic environment: alkalinity acts as a stabilizer for pH; carbon dioxide must be monitored because of its toxic effects on fish (every species can tolerate different levels of CO2); oxygen levels affect fish respiration and incorrect concentrations can slow down their growth rate; hardness is monitored because it diminishes the toxicity level of ammonia; pH also is measured to determine the toxicity level of the water; salinity is important because of its relation to dissolved oxygen. HI 3823 is supplied with all the reagents necessary to perform over 100 tests for each parameter, and relies on our popular pH electronic test, pHep, for pH measurements. The kit includes a hard carrying case, ideal for testing in the field.Check out my other items!Be sure to add me to your favorites list!SPECIFICATIONS: Dimensions440 x 330 x 100 mm (17.3 x 13.0 x 3.9")Weight2.3 kg (5.1 lb.)Multi Parameter Chemical Test Kit SpecificationsParameterRangeMethodSmallest IncrementChemical MethodNumber Of TestAlkalinity0-100 mg/L 0-300 mg/LTitration1 mg/L 3 mg/LPhenolphthalein/Bromphenol blueapprox. 110Carbon Dioxide0.0-10.0 mg/L 0.0-50.0 mg/L 0-100 mg/LTitration0.1 mg/L 0.5 mg/L 1 mg/LPhenolphthaleinapprox. 110Hardness0.0-30.0 mg/L 0-300 mg/LTitration0.3 mg/L 3 mg/LEDTAapprox. 100Oxygen, Dissolved0.0-10.0 mg/LTitration0.1 mg/LModified Winklerapprox. 110pH0.0-14.0 pHElectronic pH Tester0.1 pHN/Alife of meterSalinity0-40 g/kgTitration0.4 g/kgMercuric Nitrateapprox. 110INCLUDED REAGENTS:ALKALIAZIDEBROMOPHBLUECALMAGITE10DIPHENILHI 3810-0HI 3811-0HI 3812-0HI 3818-0HI 3835-0MANGANOUSNITRICSOLPHPHT10-- Phenolphthalein IndicatorR0009/12STARCH10-- STARCHSULPHURICCheck out my other items!Be sure to add me to your favorites list!
