Hanna HI767 Marine Nitrite Low Range Checker
Dedicated low range nitrite testing for marine water
The HI767 gives a digital nitrite result for marine aquarium samples from 0 to 999 ppb as nitrite nitrogen, NO₂-N. It uses a small prepared sample and a dedicated reagent to provide a result without matching a printed colour scale.
Choosing the right measurement
This is the marine low range model. The HI764 marine ultra low range Checker and the freshwater HI707/HI708 models have different ranges or methods, and their results and refills must not be treated as interchangeable. Keep the NO₂-N reporting form with each reading.
