The Hanna Checker® represents a good compromise between the choice of simple chemical test kits and professional quality instrumentation. Chemical test kits are not very precise as they only offer a resolution of 5 or 10 points, while professional tools can cost hundreds of dollars and require time for calibration and maintenance procedures. The Checker® is accurate and convenient.
