The Milwaukee pH55 PRO is a professional-grade waterproof pH and temperature tester built for growers. It features automatic 1 or 2-point calibration, automatic temperature compensation (ATC), and a replaceable double-junction probe for long life and fast response.

  • pH range: -2.0 to 16.0 (0.1 resolution, ±0.1 accuracy)
  • Temperature: -5.0 to 60.0°C / 23.0 to 140.0°F
  • Replaceable Mi56P probe — no need to buy a new meter when the electrode ages
  • IP65 waterproof, floats if dropped in the reservoir
  • Large dual-level LCD, ~300 hours battery life (batteries included)

Care tip: Always store with the cap full of Milwaukee MA9015 storage solution, and calibrate monthly with pH 4.01 and 7.01 buffers.
