Best ph pen
Best ph pen on the market definitely would get another one. This one is more accurate and reads the ph of the water faster than blue lab or VIVOSUN . Also calibrating this ph pen is so easy because there literally only 1 point calibrations but you could also do 2 or 3 point if you’d like.

Not accurate. Calibrates fine, but gives incorrect read outs.
Usually hanna products are great. This one for some reason IS NOT. I have 2 of these meters as well as 3 of the hanna continuous monitors......after a fresh calibration on everything that calibrated with no errors...this particular unit will not read the same values as the others. Cant be trusted, therefore it goes in the trash. Wish I would have returned it when I had the chance.
