The Bluelab EC Pen is the ultimate handy solution for measuring conductivity (aka EC or ppm) and temperature!

The Bluelab EC Pen simply tells you that your plants have the right amount of nutrient in your solution and lets you know if adjustments are needed. Measuring the conductivity every day is the best way to avoid over-diluting or over-concentrating your nutrient solution. Completely change the reservoir solution every 7 days. The Bluelab EC Pen also measures the temperature of the solution, as root health is vital to the success of a crop.

Temperature affects the growth rate and structure of a plant so a solution temperature of 18 - 22˚C or 65 - 72˚F is recommended.

The Bluelab EC Pen is a fully waterproof handheld conductivity meter that will prove to be a vital tool in any hydroponics grow room. The Bluelab EC Pen is battery operated (1 x AAA alkaline battery included) and has a backlit LCD display for easy reading.

From the Manufacturer:
The World’s favorite conductivity meter. Simply brilliant, brilliantly simple! It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can dehydrate.

Understanding the conductivity of the nutrient solution takes the guesswork out of feeding plants. It will also save you money! Using the Bluelab Truncheon® Nutrient Meter is the fastest and easiest way to measure the conductivity!

To take a reading of your solution - simply place the probe head into the solution and the reading is indicated by the flashing lights. Calibration of the Truncheon® Nutrient Meter is not required.

Meter length: 40.7cm or 16 1/32 in.
