Conductivity meter for large systems
 
Large plants require a large Truncheon! With a conductivity range of up to 6.0 EC (60 CF, 3000 ppm 500 and 4200 ppm 700), it will never leave you short.
Bluelab Commercial Truncheon is the essential tool, when growing in hydroponics, to know the level of fertilizers in the nutrient solution. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can become dehydrated. Using the Bluelab Truncheon nutrient meter is the easiest and fastest way to measure conductivity!
To get a solution reading, simply place the probe in the solution and the reading is indicated by flashing lights. Calibration of the Truncheon nutrient meter is not required. Discover also the complete list of all conductivity meters for sale on Hydroponics!
