Отзыв о Hanna Instruments HI782 25 Нитратные реагенты от Carlos Damndjperiod

Through trial and error, I found that these reagents are incredibly precise and easy to use. Using them, I was able to test nitrate levels with great accuracy and consistently receive excellent results .The chart included with the reagents is also helpful for keeping track of my data. However, they`re not the most affordable option on the market, which may deter some educators or researchers working on a tight budget..
