Oregonic Posted November 9, 2020 Share Posted November 9, 2020 Got a Hanna nitrate low range checker the other day. Worked great one time, the seal for the plastic filter housing must have fallen out into the garbage disposal when I washed it. If anyone has one of these checkers could you share a photo of what the seal looks like? I have tried 2 different o rings and they seem to seal till the paper filter is placed in it then it just leaks out when trying to push past the filter.
