  • FT 11 Penetrometer: Use this tester model for soft fruits like citrus, melons and plums to get an accurate measurement.
  • FT 444 Penetrometer: This large penetrometer model works well for hard fruits because its dial includes higher hardness measurements.

    FT327 Penetrometer

    Posted by Broc Zoller on May 5th 2016

    The manufacturer has changed the scale to feature Kg readings above lb readings VS featuring the reverse, in the past. I&#039;ll get used to it eventually, but couldn&#039;t the old dial be made available to US customers?

    Great Price

    Posted by Charlie on May 5th 2016

    For pressuring stone fruit- a penetrometer is a must and we have used the FT-327 to take pressures on thousands of pieces of fruit and they hold up great, plus the price can&#039;t be beaten.
