Bluelab EC Pen - Temperature Compensated Digital EC Tester
Bluelab EC Pen – Temperature Compensated Conductivity Tester
A meter to measure the strength of your nutrient solution is one of those really necessary items for enthusiastic hydroponics growers. Bluelab's EC Pen features the same robust build quality, accuracy and reliability that make Bluelab testing equipment the default choice for growers across the world.
How the Bluelab EC Pen Works
The Bluelab EC Pen measures the electrical conductivity of your nutrient solution via electrodes on the bottom end and then displays the measurement on an LCD display. This allows the user to fine-tune the strength of their nutrient solution for optimal plant-growth. The electrodes and temperature sensor (for temperature compensation) are protected by a slotted plastic shroud on the bottom of the unit, which is attached via a connecting chord. The Bluelab EC Pen should be calibrated before use and we also recommend that the unit is recalibrated every 10 measurements or so in order to maintain its accuracy. The Bluelab EC Pen is shock resistant and water resistant, but not fully water-proof so it should never be submerged. The unit will automatically switch itself off to preserve battery life if it is not used for several minutes.
