Built for growers, not button pushers. The Bluelab Truncheon Nutrient Meter gives you fast, accurate EC, CF and PPM readings with no buttons, no menus and no calibration required. Simply dip it into your nutrient solution and the bright LED display instantly shows your nutrient strength, helping you feed with confidence every time.
EC (Electrical Conductivity), CF (Conductivity Factor) and PPM (Parts Per Million) are all different ways of measuring the strength of your nutrient solution. Keeping an eye on these readings helps ensure your plants are getting the right amount of nutrients to thrive. Too little can slow growth and cause deficiencies, while too much can lead to nutrient burn and lockout.

Grow Tip
Plants thrive when they're fed the right amount of nutrients. Checking your EC, CF or PPM readings regularly helps prevent underfeeding (slow growth and deficiencies) and overfeeding (nutrient burn and lockout). A quick dip before every feed can save a lot of headaches later.
Pairs Perfectly With
For complete nutrient management, pair your Truncheon with the Bluelab pH Pen or Bluelab Combo Meter. While the Truncheon tells you how much nutrient is in your solution, a pH meter tells you whether your plants can actually absorb it.
Because great plants don't need guesswork—they need the right feed.
