PRODUCT INFORMATION

The Bluelab EC Pen is a temperature compensated conductivity tester, designed to measure the strength of your nutrient solution. This item is essential for growers all over the globe and with its proven track record for accuracy and reliability, you can see why.

The robust, water and shock resistant pen displays readings in 4 scales: EC, CF, PPM500 and PPM700.

How it works

The Bluelab EC Pen has electrodes on the bottom of the device, this measures the electrical conductivity of your nutrient solution. This information is then shown on the LCD display. With this vital information, you can now modify the strength of your solution with great diligence, to ensure optimal plant growth. There is a protective, slotted plastic shroud on the bottom of the device, this is attached with a connecting chord, this shroud protects the electrodes and temperature sensor, this sensor is for temperature compensation. We highly recommend you calibrate the EC Pen before use, and it is advisable that the unit is recalibrated every 10 measurements to ensure complete accuracy.

This innovative device is splash proof, but not completely waterproof so always avoid submersion.

How to use the Bluelab EC Pen 

To use the Bluelab EC Pen, make up your normal nutrient solution and stir meticulously. Then press the On/Off button, dip the end of the device into the solution and submerge the shroud, a simple tap will remove any bubbles. Keep the probe still for a few seconds and it will equalise to the temperature of the solution. When the meter has taken the reading, it will beep. You will the see the EC of the solution displayed on screen.

You can choose between Farenheit/Centigrade and PPM/EC by pressing and holding the ‘units’ button until the display begins to flash, then short click the ‘units’ button to flick through the various combinations. If you wish to determine your CF levels, just multiply the EC value by 10. You are now in a position to adjust your solution to the right strength, by either adding more nutrient or diluting the existing solution.

To turn the meter off, press and hold the On/Off button for 3 seconds. The meter will automatically turn off if it is not used for a few minutes, this is to preserve battery life. Once you have finished using the pen, rinse the probe off with fresh water and dry it before and after every test.
