A portable meter keeps the electronics in your hand and the electrode on a cable. It is easier to rinse, reaches into fermenters and narrow flasks, and takes a standard replacement probe. Most read to ±0.01 pH with three-point calibration. Pricier models store readings for brewing or QC logs, and grower models add a conductivity probe for nutrient strength.
