Bluelab EC CF Truncheon Hydroponic Nutrient Meter [Regular Scale] The World's favourite conductivity meter - the Bluelab Truncheon. 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. If the conductivity (EC) 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. Robust and reliable construction for long-lasting value Fully waterproof; splash, submerge or sink - we've got you covered Automatically detects liquids and bright LEDS indicate measurement for brilliantly simple functionality Long-format design for mixing and measuring nutrient reservoirs simultaneously No calibration required and easy to clean and disinfect All conductivity scales included – EC, CF, PPM 500 (TDS), PPM 700 Industry-leading five-year warranty for peace of mind Key Benefits of the Bluelab Truncheon EC Meter | Optimise nutrient levels All plants need access to the correct amount of food (nutrients) so that they can grow and flourish. Over- or under-feeding your plants can result in the waste of expensive nutrient resources and plant health issues. The simplest way to keep track of the amount of nutrients in your solution is to measure conductivity, which refers to the total ionic content (dissolved salts) in a solution. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity. By measuring and adjusting nutrient levels, you’ll ensure that your plants are getting the macro- and micro-nutrients they need for superior plant health. Maintenance of the Meter Keep the electrode head clean by wiping it with a soft cloth saturated in pH probe cleaning solution. PH probe cleaning solution is great for both EC and pH meters.
