The record has no confirmed CAT category and voltage pair. A marking in a photograph cannot fill that gap.

    Adds Bluetooth and the free Delmhorst EDGE app for saving unlimited readings and 123 additional species.

    Buyers who want logged, shareable readings.

Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • The JX-30 looks similar but adds Bluetooth and the EDGE app; the JX-20 has no wireless features.

Why people pick it

  • Built-in settings for 74 wood species, so most readings need no manual correction chart
  • Wood temperature correction and an internal calibration check, both stated by Delmhorst
  • Works with Delmhorst external electrodes and pins from earlier meters, so upgrading doesn't strand accessories
  • Backlit display with adjustable brightness for dim kilns and shops

Know before you buy

  • No Bluetooth or app: saving and sharing readings is manual, unlike the JX-30 with the EDGE app
  • Pin meters leave small probe holes in the wood and read only between and beneath the pins
  • Delmhorst publishes no numeric accuracy or moisture-range figure for the JX-20 on its product pages, so those are left out
