Bluelab CF Truncheon V2
The world’s favourite nutrient meter! With its super tough high quality fully waterproof design no calibration required daylight readable blue LED’s and no on/off buttons to worry about the Bluelab Truncheon Nutrient Meter has proven itself as the world leader over several years.

Convenient and easy to use meter specially designed for testing the nutrient solution.  Measuring the nutrient level via an EC meter is much more accurate than using the m/per litre method of feeding plants. Using a meter will give you more control over the amount of nutrients and additives that you are giving the plants and also it can indicate if the plants are actually uptaking the nutrients or they are being over fed. To mantain meter accuracy clean the carbon tip with the Blueab Conductivity Care Kit every two weeks.

How to use
Simply immerse the meter’s sensor into the nutrient solution and take the reading directly. Allow for the blue LED display to stop flashing so the reading will be accurate.
