Uses a 9V battery which will last 300 hours (does not have an AC adaptor but is an option if you have one)
Resolution to 0.1 pH.
Accurate within +/- 0.2 pH.
Manual 2 point calibration that I have just calibrated.
Was used for about 6 months.
I am selling cuz I have another pH monitor that has resolution to 0.01 pH with an AC adaptor.
