Calcium Hardness Checker® HC - HI720

All prices are VAT excluded and without shipping costs, unless otherwise stated.

The Hanna Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The Checker® is both accurate and affordable.
