The HI3817BP is a classroom in a backpack! The Backpack Lab Water Quality Educational Test Kit contains lessons, activities, and test kits to help students understand the importance of common water quality parameters. Using titration, colorimetry, and direct measurement, educators and students can easily measure parameters such as acidity, alkalinity, carbon dioxide, dissolved oxygen, hardness, pH, EC, TDS, and turbidity. The HI3817BP is supplied with all of the necessary reagents and equipment to perform each analysis, and all reagents and buffers are individually available as they run out. Hanna chemical test kits and pocket testers included in this Backpack Lab provide teachers with a valuable tool in helping students assess the water quality of streams, rivers, and lakes. Features at-a-glance Tests for ten important water quality parameters Classrooms can gain an extensive understanding of water quality through measurement of these ten parameters: Acidity, alkalinity, carbon dioxide, dissolved oxygen, hardness, nitrate, phosphate, pH, EC, and TDS. Complete testing setup All required materials are included with the test kit, such as the pH tester, sample beaker, indicator and reagent bottles and packets, and glass bottle for dissolved oxygen. High resolution All tests provide a high resolution based on the expected range of measurement Replacement reagents available There is no need to buy a new kit when reagents are exhausted. The reagents and buffers for each parameter can be ordered individually. Comprehensive educational material The lesson plan and components are tied together by a comprehensive teacher's manual that includes information about each parameter, classroom activities designed to introduce students to each parameter, and detailed field-testing procedures.
