Bluelab V2 Truncheon CF/EC/PPM Meter

The Bluelab Truncheon CF/EC/PPM Meter's tough, completely waterproof and famously reliable, making it the favourite nutrient strength meter of growers for years. The Bluelab Truncheon gives you an easy to read, incredibly accurate view of your nutrient strength, so you can make sure your plants are getting exactly what they need, taking you from hobbist to professional. It's no wonder that most growers choose to use a Bluelab Truncheon.

How the Bluelab V2 Truncheon CF/EC/PPM Meter works:

Growers everywhere regard the Bluelab Truncheon CF/EC/PPM as the best nutrient strength meter you can get. The Bluelab V2 Truncheon measures the electrical conductivity of your nutrient solution via electrodes on the bottom end. The Bluelab V2 Truncheon then displays the measurement on a row of LED's calibrated in all the popular scales (CF, EC and PPM). The electrodes are very high quality and will last a long time and are protected by a slotted plastic shroud.

The display LED's are a bright blue which makes them easy to read, even in daylight. The Bluelab V2 Truncheon automatically switches itself on when dipped into liquid and switches itself off when it is removed from the liquid to save battery-life. The Bluelab V2 Truncheon is pre-calibrated at the factory and has temperature compensation to ensure accuracy. The whole Truncheon is made of a super-tough, waterproof plastic and it's shape means that it can even be used to stir your nutrient solution with. Very highly recommended.

Using the Bluelab V2 Truncheon CF/EC/PPM Meter

Check out the One Stop Grow Shop Blog to find out how to control nutrient strength.

To use, make up your nutrient solution according to the nutrient manufacturer's recommended schedule and stir it well. Dip the end of the Bluelab V2 Truncheon into the solution so that the probe-shroud is submerged and then leave it there for 1-2 minutes so that the Bluelab V2 Truncheon probes can equalise to the same temperature as the solution. Remove the Truncheon and then dip it back in to take the reading. The flashing display will now give you an accurate measurement of the nutrient solution strength in CF, EC and PPM scales.

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.

Bluelab V2 Truncheon measuring range: 0.2-3.6 EC (2-36 CF) and ppm scales
