Checker đo Nitrit trong thủy sản HI764 (0 to 200 ppb)

Marine Nitrite Ultra Low Range Checker® HC - HI764

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.
