Accurate, Visual Colorimetric Water Testing for Field and Laboratory Use
The Lovibond® CHECKIT® Comparator Test Kits provide a fast, reliable, and easy-to-use solution for water quality analysis across a wide range of applications. These portable kits use a visual color matching method, with results read directly from a rotating disc calibrated against standardized color scales. This approach enables accurate testing in both field and lab environments without requiring any power supply or complex instrumentation.
Key Features
- Easy Handling: Simple reagent addition and color comparison
- Precise Reagent Dosage: Pre-measured tablet reagents ensure accuracy
- Long Shelf Life: Tablets last 5 to 10 years under proper storage
- High Accuracy: Color discs calibrated for consistent visual interpretation
- Fully Portable: Designed for onsite testing in tough environments
- No Power Required: Ideal for field testing or remote areas
How It Works
- Fill sample cell with water.
- Add reagent tablet(s).
- Insert the sample into the comparator.
- Rotate the disc until the color matches.
- Read the concentration directly through the viewing window.
Typical Applications
- Boiler and Cooling Water Treatment
- Disinfection and Chlorination Control
- Drinking Water and Potable Water Monitoring
- Swimming Pool and Spa Maintenance
- Galvanization and Electroplating
- Food and Beverage Water Analysis
- Wastewater Compliance Testing
