Folks,
I have a Hanna HI 96713 Low Range Po4 photometer, and unsure of which reading is correct. The included cuvette is marked at 10m/l, but is not accurate. I have tried testing both using the 10m/l level marked on the cuvette, and filling the cuvette with a digital pipette set to 10m/l. I get the following readings:
Using 10 m/l on cuvette: Po4 is 0.01
Using pipette: Po4 is 0.04
Any ideas on which reading to trust? Disappointed that Hanna provides an inaccurate measurement.
Any advice is appreciated!
