The Hanna HI3812 Total Hardness Test Kit measures mineral concentrations through chemical titration. It quantifies calcium carbonate from 0 to 300 mg/L for 100 separate tests. Romanian manufacturing standards maintain reagent stability for precise water quality testing.
Key Features
- Dual-Range Sensitivity: 0.3 mg/L resolution for low-range and 3.0 mg/L for high-range. Detects minute mineral shifts in water.
- EDTA Titration Method: Chemical reagents include 120 mL EDTA solution and 30 mL buffer. Supports accuracy for industrial boiler water testing.
- Comprehensive Hardware: Kit contains 20 mL and 50 mL beakers with syringes. Withstands impact during field use in road dust.
- 100 Test Capacity: Reagent volumes support one hundred individual water quality assessments. Reduces frequent restocking for remote sites.
Frequently Asked Questions
How to use Hanna HI3812 test kit?
Add the water sample to the beaker and titrate with EDTA until the color changes. The syringe scale indicates the total hardness in mg/L CaCO3.
What is the range of HI3812?
The kit measures between 0.0 to 30.0 mg/L and 0 to 300 mg/L. This covers both soft and moderately hard water types.
