About this item

  • 3-IN-1 METER: Includes two 8-inch probes and sensor for measuring (1) moisture (2) sunlight and (3) pH level
  • COMPOST BIN MUST-HAVE: Maintaining your worm compost bin is made easier with this 3-in-1 meter; simply set the switch to the desired mode and insert the probes into bedding of the worm bin
  • MEASURE MOISTURE: Ensure the worm bed has just enough moisture; too much moisture in the bedding can lead to worms drowning or fleeing, unpleasant odors, and increased acidity
  • MEASURE LIGHT: Worms are light-sensitive and will bury themselves in the bedding to avoid light; light can be used strategically to prevent worms from wandering (especially in a new environment)
  • MEASURING pH: The pH level should be slightly acidic and maintained between 6.0 – 7.0; too much acidity can cause sour odors and lead to protein poisoning in composting worms


Worm Nerd’s 3-in-1 Worm Bin Meter is the ultimate tool for ensuring the conditions of your worm compost bin are ideal and your worms’ needs are being met. Composting with worms typically means maintaining four main environmental elements in the worms’ bedding: moisture, light, pH level, and temperature. Each is important and should be assessed on a regular basis. With Worm Nerd’s 3-in-1 Worm Bin Meter, moisture, light, and pH level are measured with just one portable, lightweight tool.

Kinda funky but works, compared it with a friends more expensive tester and it was close enough for my purposes.

The size of the thermostat makes it easy to read

What a small but great addition to my gardening tools. I have Japanese maples and plumerias. So as some of you well know it’s very important not to over water them. This little meter stops all the guess work.
