The Prerna Hardness Kit for Hard Water Testing is a simple and effective solution for monitoring the performance of your water softener and checking the hardness level of water.

It comes with 4 reagent bottles and can perform up to 200 tests, making it a highly economical and long-lasting option. The testing process is user-friendly—just add the reagents as directed into a water sample and observe the color change to determine the hardness level. The reagents are clearly labeled for hassle-free handling, and the results are reliable enough to help you know when to adjust or regenerate your softener system. Compact and portable, this kit is a handy tool for households, offices, labs, water treatment plants, and industrial users who need to keep a regular check on water quality.
