CHECKER HC ®

CHECKERS55f944749efc9

The Hanna Checker® HC (Handheld Colorimeter) 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.

 

What is colorimeter?

Be sure that the distilled or DI water is used in step one of the instructions. Purchased distilled or DI water sometimes has electrolytes added back in. These electrolytes are usually forms of calcium and magnesium. This will cause a false high reading during this test.
