Checker đo Đồng Hanna HI747 thang thấp (0 đến 999 ppb)

Copper Low Range Checker® HC

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.

Features at-a-glance:

• Easier to use and more accurate than chemical test kits
• Dedicated to a single parameter
• Small size, big convenience
• Ideal for: Water quality, Environmental, Plating, Education
