Boiler and Feedwater Combination Test Kit

The HI-3827 boiler and feedwater chemical test kit measures 6 main parameters; alkalinity, chloride, hardness, pH, phosphate and sulphite.

All the tests are performed with a titration method except for the pH test. pH is obtained with Hanna's pHep®, pH electronic tester which guarantees greater accuracy and a longer life than traditional litmus paper.

This kit is equipped with all the necessary reagents and equipment to perform over 100 tests (50 for phosphate). All tests are easy to perform with step-by-step instructions and the kit is supplied with a rugged portable carrying case for orderly transportation.

Significance of use

Monitoring the alkalinity, chloride, hardness, phosphate, pH, and sulphite concentrations in boiler and feedwater is essential in preventing hazardous or costly situations.

These parameters are important in determining the corrosive characteristics of water due to carbonates and chloride.

Sulphite is critical to prevent pitting and oxidation of metal components. A high level of sulphite results in a lowered pH, which can also promote corrosion.
