Hanna Instruments-3817 General Water test kit
Supplied complete with everything you need in a rugged case, this general water test kit allows you to test and measure for Alkalinity, Chloride, Hardness, Iron, pH and Sulphite.
Water Quality Test Kit
The HI-3817 combination test kit offers all the necessary equipment for accurate and reliable water quality testing. This kit allows you to monitor the most important chemical parameters in water: alkalinity, chloride, hardness, iron, pH and sulphite.
This test kit has all the reagents needed to perform over 100 tests for each parameter (50 tests for iron). pH measurements are performed with our electronic pHep® pH tester which guarantees more accurate and repeatable readings than litmus paper.
The chemical reagents to perform each test are provided in numerically labelled bottles and are easy to identify. All titration reagents are standardised, and do not require chemical handling to perform the analysis. The HI-3817 is supplied with a convenient hard carrying case, designed with field applications in mind. It will also keep your test kit neat and organised.
