HI 3823 Marine science test kit (alkalinity, carbon dioxide)

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 fundamental role in the correct balance of the aquatic environment: alkalinity acts as a stabilizer for pH; carbon dioxide must be monitored because it is a toxic element for fish (every species can stand different levels of CO 2 ); oxygen levels affect the 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 and salinitiy is important because of its relation to dissolved oxygen. This test kit is supplied complete with all the reagents necessary to perfom over 100 tests of each parameter, and relies on the popular pH electronic tester, pHep®, for pH measurements. The kit is supplied in a hard carrying case, ideal for testing in the field. Spare reagents are available individually.
