The measurement of your nutrient solution is key if you want to get the best results. When you add nutrients to your water you increase the conductivity; the potential for electricity to move through the solution. By measuring this we can therefore get a clearer picture of concentration of the solution and tailor this to the plants requirements or accurately follow a nutrient schedules recommendations. The nutrient solution can now adjusted to bring it to the correct strength by adding more nutrient or by diluting with water as necessary. Always rinse the probes with fresh water after every use and clean them once a week with an appropriate cleaner such as the Bluelab Conductivity Probe Cleaning Kit to maintain accuracy, reliability and probe-life.

Unfortunately the answer is no, the truncheon is purely for measuring EC/CF. The Bluelab pH pen is sold seperately, you can find this here. Possibly the simplest nutrient meter to use. No buttons just immerse the probe in your nutrient solution, the meter will automatically turn on and display a reading along the shaft. Remove the meter from the water and it will turn off. It really is that easy! The display LED's are a bright blue which makes them easy to read, even in daylight.

If the Truncheon fails to illuminate any LEDs when immersed in solution, the batteries should be changed.

Then, leave the Truncheon in a warm, dry place with the cap removed to allow it to dry out. Ensure the O-ring is present and intact. If corrosion is noted, consider replacing the Truncheon. The Truncheon will not turn on if the conductivity of the solution is not higher than 0.2EC. Add more nutrients to your solution and re-test. Wait for the probe to come to the same temperature as the solution. Keep the probe in the solution for 1-2 minutes. when your ready to harvest and your flushing what should the reading be? and if i take a reading when im growing how will i know om giving it the correct amount of feed is there a chart or something telling you does it give you the reading on the truncheon?Place 1 or 2 drops of Conductivity Probe Cleaner on the probe face. Rub firmly with a Bluelab Chamois. 3: Rinse the probe face While it was designed for daily use, rest assured that the Bluelab Truncheon Nutrient Meter will be your lifelong companion on your gardening journey.

Bluelab are renowned for producing the most accurate and reliable measuring devices. How To Use The Bluelab Nutrient Truncheon The Bluelab Truncheon measures the electrical conductivity of your nutrient solution through electrodes on the bottom end. The electrode reads the water, compensates for the water temperature (very important for an accurate reading), then the measurement is displayed in a simple, easy to read format via the row of LED’s along the shaft. The Truncheon displays readings in every form of measurement; EC, CF, PPM and TDS. Bluelab Truncheon Nutrient Meter: Your Key to Nutrient Optimization Why Measure Conductivity? Fueling Plant Growth
