Hanna Checker® HC Portable Colorimeters

The Hanna Checker® HC 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® HC is both accurate and affordable. The contoured style of the Checker® HC fits in your palm and pocket perfectly, while the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.

  • Easier to use and more accurate than chemical test kits
    • High accuracy
    • Large, easy-to-read digits
    • Auto shut-off
  • Dedicated to a single parameter
    • Designed to work with Hanna’s reagents
    • Uses 10 ml glass cuvettes
  • Small size, big convenience
    • Weighing a mere 64 g (2.25 oz.), the Checker®HC easily fits in your palm or pocket
  • Use for quick and accurate on-the-spot analysis
  • Single-button operation: zero and measure
  • Operated by a single AAA battery
