Not quite as accurate as my bluelab ph meter but gives a much faster readout and includes ppm as a bonus.

I purchased this unit for myself so I could give my current unit to my son. It has everything you need to test PH and EC all in one. I tested against my truncheon, and it's just as accurate for EC. I would recommend this meter to anyone needing to test water for many applications.
