What we liked

  • + The glass spear tip is made to penetrate liquids, semi-solids and soft solids, and sourdough is named in the listing.
  • + Bluetooth connection lets you read and log results in a phone app to compare one bake with the next.
  • + Built-in ATC and a temperature reading alongside pH on the display.

Trade-offs

  • - Stated accuracy is plus or minus 0.1 pH, coarser than the 0.01 quoted by some other meters in this guide.
  • - The listing bullets do not say whether calibration solution is included or whether the probe is replaceable.
