More of an fyi just to let those who bought LR Hanna test kit first and need to conduct the dilution process vs newly purchased Hanna HR kit that the results are within 1(ish) ppm. So use up your low range kit and dilution process w confidence to save a few bucks. The HR kit is sooo much easier though if haven’t bought either yet. (Remember LR requires multiplying by 10 so 19 ppm vs 17.8 on HR kit).
