What is pH Meter with Replaceable Probe

Pocket pH meter reading −2.00 to 16.00 pH at ±0.01 accuracy, with automatic temperature compensation and auto-recognizing 1–3 point calibration across five buffer standards. The glass probe module is user-replaceable, so the meter outlives its electrode.

IP67 waterproof body that floats if dropped; backlit display; roughly 2000 hours on four AAA batteries. Kit includes calibration buffers and a carrying case.
