Total Hardness of Water Test Kit – 100 Test

Total Hardness of Water Test Kit – 100 Test 1Box



The RMR-2003 is a titration-based chemical test kit that determines the total hardness concentration in two ranges: 1 ppm/drop and 5 ppm/drop. The calculation formula also provided so that user may choose any ranges. The RMR-2003 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents to perform approximately 100 tests.

Features at-a-glance

  • Complete setup
    • All required materials are included with the test kit, such as the sample beakers and reagent dropper bottles.
  • Confident result
    • Easy, Quick and accurate test results with Economical and Authentic way.
    • Drop counting Method. No need of Calculator just count the drop and multiply by 1 or 5 as required.
    • 1 Drop = 1 ppm or 5 ppm or your choice by provided formula.
  • Flexible resolution
    • The great easiest formula is opened to user. User may choose any resolution by changing only the sample volume. (eg, 10 ml sample=5ppm/drop, 50 ml sample= 1ppm/drop and so on.)

Significance of Use

Water hardness has traditionally been defined as the capacity of water to precipitate soap. The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. Thus, water hardness is actually a quantitative measure of these ions in the water. It is also now known that certain other ion species, such as iron, zinc, and manganese contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes.
