Heating systems and cooling towers require constant monitoring in order to function efficiently.
The correct equilibrium of the most important chemical parameters such as alkalinity, chloride, dissolved oxygen, hardness, phosphate and sulfite must be maintained.
This guarantees the maximum efficiency of the system and prevents costly damage that can occur as a result of corrosion to metal parts
HANNA®'s combination test kit, HI 3821, includes all the necessary reagents to test these parameters. The kit allows you to perform over 100 tests for each parameter (50 for phosphate). All reagent bottles are numerically coded for ease of operation and will allow you to avoid mistakes.
HI 3827 kit is for alkalinity, chloride, hardness, pH, phosphate and sulfite.
All the tests are performed by a titration method, with the exception of the pH test which is obtained with HANNA®'s pH electronic tester, pHep, which guarantees more accuracy and longer life than traditional litmus paper.
Every kit is equipped with all the necessary reagents and equipment to perform over 100 tests (50 for iron and phosphate), and all the reagents can be purchased individually as they run out. All tests are easy to perform with step-by-step instructions.
Every kit is supplied with a rugged portable carrying case for easy transportation.
