The Bluelab Truncheon has continued to prove itself as the best nutrient meter on the market. This simple and reliable device gives you an accurate, easy to read view of your nutrient strength. This allows you to meticulously monitor your nutrient solution to ensure your plants are getting exactly what they need. This product instantly elevates you from hobbyist to professional, delivering you healthier, more robust plants.
How it works
The Bluelab Truncheon measures the electrical conductivity of your nutrient solution through electrodes on the bottom end. The measurement is then displayed on a row of LED’s, even visible in daylight. It is possible to calibrate the truncheon in all the popular scales (CF, EC and PPM). The electrodes are protected by a slotted plastic shroud, this ensures they have great longevity.
The Bluelab Truncheon will automatically turn on when it is dipped into liquid and turned off when removed from liquid, essentially saving battery. The innovative, pre-calibrated truncheon is equipped with temperature compensation to ensure accuracy.
How to use the Bluelab Nutrient Truncheon
Make up your nutrient and stir well. Then take the end of the Bluelab Truncheon and submerge the probe shroud for around 1-2 minutes. This makes sure the truncheon probes can equalise to the same temperature as the solution. Remove the Truncheon and dip it back into your solution to take the reading. The display on the truncheon will now be flashing with an accurate measurement of the nutrient solution in your preferred scale, either CF, EC or PPM. You can now adjust your nutrient solution by adding more nutrient or diluting it with water. We highly recommend you rinse the probe with clean water after each use and clean it once a week with an appropriate cleaner. The Bluelad Truncheon Measures in EC (0.2 - 3.6), CF (2 - 36) and ppm (TDS and 700 scale), has a battery life of minimum 1 year and comes with a 5 year guarantee.
