Iron Checker HC
How the Iron Checker HC Works:
No More Guesswork or Waiting for Results! The HANNA HI 721 Iron 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 HANNA HI 721 Checker®HC is accurate and affordable with immediate results.
