Hanna Instruments Total Hardness ( 0-150 mg/L) LR Chemical Test Kit – HI3840
A chemical test kit called the HI3840 evaluates overall hardness as CaCO3 through titration with EDTA. All of the supplies and tools needed to accomplish about 50 tests are included with the HI3840.
- prepared reagents for simplicity of use
- For traceability, every reagent is marked with an expiration date and a lot number.
- According to manual titration using a colour indicator, other ion species like iron, zinc, and manganese contribute to the total hardness of the water.
- To avoid scaling and clogging water pipes, water hardness must be measured and subsequently controlled.
