Review on Hanna Instruments HI764 Nitrite Checker by Alex Taylor
but I recommend using their lab water, my RODI reads 0.
Very accurate when done correctly and readings match, but use of their lab water is recommended. My RODI reads 0 TDS but shows different results than your water. Also, the aquarium water sample is tiny compared to the stock solution, so any measurement error will get the situation out of the way.
- Very good value for money
- Piggy bank price
